Yes, I agree. A variant of sigwaitinfo that will return multiple queued
signals was mentioned ages ago, but because the siginfo structure is
much larger than is needed, that isn't a very effective use of cache.

Something specialised for fd events is more appropriate IMO. Large
numbers of queued RT signals aren't used for anything else AFAIK anyway,
not even timers.
