FWIW, upon looking at this more closely, I would rather see this patch
of yours fix the timeout problem. This actually has nothing to do with
illegal addreses but with any situation where the SA returns failure
(ie MLID exhaustion, etc)

There is already a per-event increasing back off, it just needs a
little fussing to keep track of time properly and sort the list by
expiration.
