Why do you assume that a non-threaded MUD that is using poll/select
will actually be doing polling? There have been lots of techniques
discussed, none of which do actual polling. I don't recall any of the
dev-mud versions using polling (I'm quite sure mine doesn't). The
name 'poll' can be quite misleading. Semantically it is very close to
the WIN32 WaitForMultipleObjects - it wakes up when any of the fd's
is active, or when the time limit expires. If the time limit is set
based on needed MUD events, then there is no polling.

Don't design inefficiency in - it'll happen in the implementation.
