Maybe used by caller, trying to open mmap() on NFS, Lustre or
Panasas (thanks Sam).
For now, this is used to warn about the usage of mmap on such FS.
Please note, that Ralph mentioned the orte_no_session_dir parameter.
The help message includes a reference to this.

anything for non-MPI apps. Oops! (But before you freak out, gentle
reader, note that mpi_paffinity_alone for MPI apps still worked fine)
When we made the switchover somewhere in the 1.3 series to have the
orted's do processor binding, then stuff like:
mpirun --mca mpi_paffinity_alone 1 hostname
should have bound hostname to processor 0. But it didn't because of a
subtle startup ordering issue: the MCA param registration for
opal_paffinity_alone was in the paffinity base (vs. being in
opal/runtime/opal_params.c), but it didn't actually get registered
until after the global variable opal_paffinity_alone was checked to
see if we wanted old-style affinity bindings. Oops.
However, for MPI apps, even though the orted didn't do the binding,
ompi_mpi_init() would notice that opal_paffinity_alone was set, yet
the process didn't seem to be bound. So the MPI process would bind
itself (this was done to support the running-without-orteds
scenarios). Hence, MPI apps still obeyed mpi_paffinity_alone
semantics.
But note that the error described above caused the new mpirun switch
--report-bindings to not work with mpi_paffinity_alone=1, meaning that
the orted would not report the bindings when mpi_paffinity_alone was
set to 1 (it ''did'' correctly report bindings if you used
--bind-to-core or one of the other binding options).
This commit separates out the paffinity base MCA param registration
into a small function that can be called at the Right place during the
startup sequence.

long-standing bugs (see trac ticket list below). They're currently
somewhat obscure bugs, but are becoming much more relevant in a world
where OpenFabrics devices fail and you replace them with a newer model
(i.e., the cluster is homogeneous... ''except'' for where you had to
replace one or two OpenFabrics devices, and the same model is no
longer available).
This commit includes a '''lengthy''' comment (that we spent a lot of
time writing!) about what exactly it does and does not do. The
previous code was rather short and '''incredibly''' subtle. The new
code is slightly longer, but is both much more explicit and much more
painstakingly documented.
This commit fixes multiple trac tickets. The real one that we fix is
#1707; the others are fixed as a side-effect. In short: fixing #1707
prevents Bad Things from happening later in the startup sequence.
Fixes trac:1707, #2164, #1574.

Not having this check was causing distcheck errors on the OMPI
tarball-build machine because it's still a 32-bit-default machine, so
the evutil.c code was failing some #if conditionals (since it didn't
think it had strtoll available).

Have orte call setpgrp after forking (but before exec) when

If a SIGTSTP arrives before the processes have been launched, then
record it and suspend them right after launching.
