@jsquyres Reminder to review

[yosefe]

@bwbarrett Was it really the intention to bump the age of liboshmem_so_version from 30 to 31?
Seems that because of this change, liboshmem.so.40 was changed to liboshmem.so.39 (in latest build of openmpi rpm), which breaks yum upgrade.

@jsquyres should we open a new issue for this?
liboshmem_so_version=70:3:30 -> liboshmem_so_version=70:4:31: the age change (30 -> 31) while current (70) is the same caused SONAME changes (70-30=40 -> 70-31=39) liboshmem.so.40 -> liboshmem.so.39 which as mentioned above by Yossi breaks package manager dependencies (e.g. yum update fails). Unless it's intentional, it looks like a bug.

@yosefe @artemry-nv Yes, we probably need an issue for this. @bwbarrett and I have been discussing what we're going to do to fix this...
