How about in the reverse ... being able to have multiple
processes able to dynamically connect to a single existing sigfd
and listen for a signal? You said that you want to reserve write()
for sending signals through the sigfd. If you implement the
write(sigfd, ...) then this seems to provide a very nice writer/reader
signal deliver interface with well defined end points for the sender
and receivers. Or maybe I'm just confused.
