Well, how about the kernel passes siginfo and siginfo_cancel events
up to userland, siginfo will remove any siginfo's from its buffer
that it sees a siginfo_cancel event for -- naturally we need a flag
to tell siginfo when to poll for events, this flag would be
set by the function which cancels siginfo's. Would this work? Is
it worth the complexity?
