Step back for a moment. I know of phttpd and zeus. They both have
a serious problem: they fall down when the load on the system exceeds
the capabilities of the cpu. If you'd bother to take a look at the
aio api I'm proposing, it has less overhead under heavy load as events
get coalesced. Even then, the overhead under light load is less than
signals or select or poll.
