We also have the alternative of pushing the responsibility of notifying the CM 
of the event to the ULPs, which is what's done today.  The problem there is that 
gets pushed up to all userspace applications as well.

And even with these proposed changes, there's a race condition where the CM can 
timeout a connection after data is received over it, but before this event can 
be processed.  This makes me wonder if any of this is worth it...
