There were several issues preventing the openib btl from running in
thread multiple mode:
- Missing locks in UDCM when generating a loopback endpoint. Fixed in
open-mpi/ompi@8205d79819.
- Incorrect sequence numbers generated in debug mode. This did not
prevent the openib btl from running but instead produced incorrect
error messages in debug builds.
- Recursive locking of the rcache lock caused by the malloc
hooks. This is fixed by open-mpi/ompi#827
