* c) the inability to handle fork or file descriptors (think dup)
* limits the applicability over poll, so this is not a generic
* poll replacement.
* d) epoll doesn't work the same as select with many file descriptors
* (such as files). while not critical, no other advanced interface
* seems to share this (rather non-unixy) limitation.
* e) epoll claims to be embeddable, but in practise you never get
* a ready event for the epoll fd.
*
* lots of "weird code" and complication handling in this file is due
* to these design problems with epoll, as we try very hard to avoid
