Yes and no. They are different code paths, so I can see how different
verbs are used, and different control buffers are passed during the
sequence. It's probably either a missed valgrind annotation in
libibverbs or something that OMPI is doing (where we *hopefully* have
valgrind annotations in v1.3...).
