What is the OS support for waitid
(http://man7.org/linux/man-pages/man2/waitpid.2.html)? Seems to
have support for async waiting of multiple processes (at least
it can return immediately if no child has exited). One
consideration is how responsive you need to be to a process
exiting -- is it ok for example to be notified 500ms after the
process exits? If so, you can interleave timed waits for socket
data with a check to see if any process exits. I've done this
in the past for such things. I don't know how well this works
for libevent though.
std.process has tryWait() if polling were acceptable, but I would
really like to avoid it. Or have I misunderstood?
