This mpool will have no btl module owner there was no btl created for
the HCA with no ports, but it will still be tracked in the mpool
framework (i.e., it's available).
If MPI_ALLOC_MEM is called by the app, one of two things will happen:
1. if there's an HCA on the host with some active ports, the openib
btl component will still be in the process space, and therefore
the "mpool with no btl" (MWNB) module will still be able to call
the reg/dereg functions, and all will be fine. However, if
MPI_FREE_MEM is never invoked to free the memory, bad things will
happen during MPI_FINALIZE. The pml is finalized, which finalizes
all the btls. The btls finalize all their mpools and all is fine.
But later we close down the mpool framework which then finalizes
any left over mpool modules, such as MWNB. However, the openib
BTL module functions that the MWNB was registered with are no
longer in the process space, and it segv's while trying deregister
the memory.
2. if there are *no* HCA's on the host with active ports, then the
openib btl will have been unloaded, and when the MWNM tries to
register the memory, the functions it tries to call (in the openib
btl) are no longer there, and we segv.

it to at least compile. If you actually get to the point of invoking
the openib btl progress thread, you'll get a big opal_output warning
that it is pretty much guaranteed not to work.

Cleanup ALL instances of output involving the printing of orte_process_name_t structures using the ORTE_NAME_ARGS macro so that the number of fields and type of data match. Replace those values with a new macro/function pair ORTE_NAME_PRINT that outputs a string (using the new thread safe data capability) so that any future changes to the printing of those structures can be accomplished with a change to a single point.
Note that I could not possibly find outputs that directly print the orte_process_name_t fields, but only dealt with those that used ORTE_NAME_ARGS. Hence, you may still have a few outputs that bark during compilation. Also, I could only verify those that fall within environments I can compile on, so other environments may yield some minor warnings.
