* Waiters are herders of connections: They monitor a large number of
* connections and react if data arrives, the connection is closed or
* if nothing happens for a specified timeout period.
*
* The "poll" waiter should be portable to just about anything, but it
* is not very efficient because it has to setup state on each call to
* poll(2). Almost all kernels have made better facilities for that
* reason, needless to say, each with its own NIH-controlled API:
*
* - kqueue on FreeBSD
* - epoll on Linux
* - ports on Solaris
*
