Agreed, both interfaces are useful. You see that epoll_wait is optimised for one in particular though.
Curiously. I'll probably continue to use a calculated relative timeout instead of using a POSIX timer, as the overhead of setting up and tearing down the latter is more system calls which we still like to avoid if it's not hard.
