Sorry, this sentence has me baffled. Are you unable to reproduce the
problem before the fixes or afterwards? The first step is to reproduce
the problem, right? To do so:
A) Back out r20944. Easy way to do that is just
% setenv OMPI_MCA_mpool_sm_min_size 0
B) Check that osu_bw.c hangs when using sm and you reach rendezvous
C) Introduce your changes and make sure that osu_bw.c runs to completion.

osu_bw.c hangs for me. The PML fix did not seem to work.
