2. fix for MPI_Free_mem, was calling deregister but never called mpool_free.. so
we leaked memory. Still an open issue here though, if the memory is alloc'd
and the mpool doesn't create and cache a registration, we will never find the
mpool to free with.

derefence through it. It is legal for endpoint_addr to be NULL in the
destructor because if btl_tcp_add_procs() -> btl_tcp_proc_insert()
returns UNREACH, then endpoint_addr will be NULL and we'll OBJ_RELEASE
it.

easier to do event accounting that way
* greatly increase receive event and buffer sizes. We're still about half
of what Cray defaults to, so I don't feel bad about the increases
* Implement a pre-pinning optimization for eager fragments - will be
pinned on first use and left pinned for the life of the fragment
* Since we can't have two receive frag callbacks fired at the same time,
don't have receive free list - just keep one receive fragment in the
module. Saves a big free list and all that interaction.

things I found:
- Locking should prevent it from happening (I think), but there was a
race condition in the component progress -- a callback could be
triggered that would free the request before it was off the outstanding
requests list.
- When pulling a request off the component free list, make sure to
reinitialize the free_called state on the IO request. This was
what was causing Edgar's failures
- In the request cleanup code, pull the request out of the per-
component free list before returning to the free list. This
probably would cause asserts to fire, although it looks like
I wrote the loops such that it would have been memory safe if
the asserts didn't fire. Not really sure why I did that, but
let's try it again...
This should go to the v1.0 and v1.1 branches.

right now. Some testing on large NUMA machines should be done in order
to make sure that we need to export this variable out to the MCA layer.
This commit was SVN r9868.
- We had a bad conditional choice, such that asking for pvfs2 would
result in pvfs trying to build as well, which was going to fail.
- We didn't try to link in the libray for PVFS2's adio component.
- We were clobbering romio_flags, so it was impossible to pass
flags to romio (like the selection of filesystems)
This commit was SVN r9854.
- LDFLAGS set at the top level of Open MPI were not passed to the
ROMIO configure script
- If ROMIO was explicitly required (with --enable-io-romio) and
not able to be built, abort OMPI's configure script.
This needs to go to the v1.0 and v1.1 branches.
This commit was SVN r9845.
- change MASK behavior for tags - we need the upper bit to be whether
the tag is reseved or not. MPI_ANY_TAG should not pull off any
reserved tag communication
- some other random debugging output to try to get some idea what is
spewing out of here.

message from a known peer (not MPI_ANY_SOURCE) then we can attach the
remote proc and initialize the convertor as soon as we know the data-type,
and the count (so basically in the _INIT macro). If it's not the case, then
create them in the _MATCHED macro (as in the original version). Of course,
beforeinitializing the convertor we check that there will be some data
in the message.
This commit, plus the convertor improvements from few days ago, lower the
latency for my test case environment (mvapi) by 0.1 microseconds. The convertor
now is as slim as it can be, I don't think there is anything else to
remove/improve.

the memory descriptor is closing itself, so that it actually works properly ;). I think I
was just getting lucky and not sending enough short messages with the reference impl.

* It appears that Cray's SeaStar has some horrible performance for iovecs - IN_pLACE
was actually slower than copying into eager frags. Ugh. And we don't even pre-pin
eager frags yet!
