I sympathize, but the reality is that the current infrastructure

It's not like we're getting rid of the syscall.  I'll be behaving
exactly as it does today: returning the error code that indicates that
cancellation failed because it lost the race with completion.  Every
caller has to cope with that to use cancel safely.

Yes, I realize it doesn't work today.  But hopefully we'll be able to
reimplement it in a cleaner way.  That's why I said, I hope we don't
give up on the functionality of aio_cancel --- not that I'm against
removing what we currently have.
