remaining changes are in event.c and event.h, plus everything in the
WIN32-Code directory. I still have to find a way to make it working on
Windows without these changes, but I have good hopes. However, the
the code in WIN32-Code will have to stay there as it's more stable
than the one provided by the libevent project.

as we can have multiple threads in the event library if there are multiple
MPI threads. Well, we could, once I fix the need for the lock in
opal_progress(), which should happen shortly. Anyway, we need to use the
same locking scheme throughout the code, and the device support was
already using the OPAL_THREAD__{lock,unlock} macros, which only go
active when we think there are multiple threads we care about.
Also, stop duplicating the OPAL_THREAD_SCOPED_LOCK macro's functionality
and use it in a bunch of places in the code.

currently used in the Open MPI project, so it's safe to remove them from the
Windows library. But, they should be never used otherwise changes are
required.

range of OS friendly path management functions, such as opal_basename
opal_dirname. They should always be used instead of basename and
dirname. There are several functions which allow us to create paths
that are compatible with the OS.
The OPAL_ENV_SEP define should be used (instead of ':') when a env
variable is splitted.

One of the most important is the IOVBASE_TYPE which should be used
all over the places for casting to and from the iov_base field of
the iovec struct. The reason is because windows does not support
any kind of implicit conversion (not even through void*). All
conversions should be EXPLICIT.

- The HOME on Windows is called USERPROFILE.
- C++ compilers (at least on Windows) require explicit casts. Even going

So define the constant if it isn't already defined. Something else

did pre-libevent update. The problem is that the behavior of
OPAL_EVLOOP_ONCE was changed by the OMPI team, which them broke things
during the update, so it had to be reverted to the old meaning of
loop until one event occurs. OPAL_EVLOOP_ONELOOP will go through the
event loop once (like EVLOOP_NONBLOCK) but will pause in the event
library for a bit (like EVLOOP_ONCE).

Keeping the cache misses as low as possible is always a good approach.
The opal_list_t is widely used, it should be a highly optimized class.
The same functionality can be reached with one one sentinel instead
of 2 currently used.
I don't have anything against the STL version, but so far nothing can
compare with the Knuth algorithm. I replace the current implementation
with a modified version of the Knuth algorithm (the one described in
The Art of Computer Programming). As expected, the latency went down.

After seeing the uglyness that is removing directories in the
codebase I decided to push down this to the OPAL by extending the
opal/os_create_dirpath.(c|h) to contain some more functionality.
In this process I renamed 'os_create_dirpath' to 'os_dirpath' since it
is a bit more general now.
Added a few functions to:
- check if an directory is empty
- check to see if the access permissions are set correctly
- destroy the directory at the end of the dirpath
- By using a caller callback function (a la Perl, I believe)
for every file, the caller can have fine grained control over
whether a specific file is deleted or not.
This simplifies things a bit for orte_session_dir_(finalize|cleanup)
as it should no longer contain any of this functionality, but uses
these functions to do the work.
From the external perspective nothing has changed, from the
developer point of view we have some cleaner, more generic code.

opal_free_list_item_t and everyone was just treating them as
opal_list_itme_t structures, which meant that they were overwriting the
user_data memory anyway. So make an opal_free_lsit_item_t be just a
opal_list_item_t.
Also, opal_free_list_item_t wasn't a proper class, which made it slightly
less than nice to use, so fix that part up. Also update the
opal_free_list_t to use the class macros, so that it is more obvious we
actually do the right thing.

reentrant for free(), so we can't call free() from inside an sbrk() handler.
The solution is never call sbrk() with a negative number. The mmap() allocator

memory back to the OS as soon as possible.
This should go to both the v1.1 and v1.0 branches.

Previous rev. maintained state on the communicator used for acking duplicate
fragments, but the communicator may be destroyed prior to successfull
delivery of an ack to the peer. We must therefore maintain this state
globally on a per peer, not a per peer, per communicator basis.
This requires that we use a global rank on the wire and translate this as
appropriate to a local rank within the communicator.
