OK, I guess this is a theoretical problem -- but with our current 60
second timeout, is there really much chance of this?

And do we have much chance of recovering from a command completing
after we gave up on it, given that we probably free the mailbox
(meaning the HCA can scribble on memory that's now been reused for
something else, etc)?

I guess I could queue this for 2.6.22 since it probably doesn't hurt,
but I don't see any reason to put it in 2.6.21.
