Wait, I lied -- sorry.
opal_progress will call the bml progress, which then calls each of the
btl processes (or we changed it so that opal_progress directly calls
each btl progres -- I forget which). So technically opal_progress
will see that "something" happened. But what that "something" is is
unknown -- it could be a control message, or somesuch.
(I don't recall offhand what the openib btl's progress function returns)
