In working on https://svn.open-mpi.org/trac/ompi/ticket/1434, I see
fairly inconsistent use of the mca_openib_btl_component.ib_lock, such
as within btl_openib_proc.c.
In fixing #1434, do I need to be mindful doing all the locking
properly, or is it already so broken that it doesn't really matter,
and all I need to do is ensure that I don't put in any bozo deadlocks?
