Hmmm, the only problem I can see in the aio code wrt timer usage is
the following. Does this patch make a difference? If not, I'm guessing
that the problem is something in SMPtimers-A0 that aio happens to
trigger. The only timer aio uses is for the timeout when waiting for an
event, and the structure for that is put on the stack.
