Recursive mutex, to me, means "grant more of whatever the requesting thread already has, basically as a no-op." The calling thread isn't really acquiring anything new. Blocking him on something he already holds is a guaranteed deadlock. Whatever he's asking is for is probably going to help run his operation to completion, so it probably reduces contention on the exclusive lock too.
