 To be honest, I do not know why the POLL_* constants are defined at all.
 The kernel never generates SIGPOLL, and it is an obsolescent feature in
 POSIX. Their main effect seems that someone can use POLL_IN instead of
 POLLIN and have a hard time debugging.
 
 How are you using these constants? :)
