I'm not against the intent, just the implementation as it stands - select()
needs to be fast IMHO to be of any use. Any optimisations that you can
think of would be excellent. For instance thread pooling etc. I also think
that select() si too heavyweight the way it creates all these objects and
frees them for every call. select() is likely to be called with the same
arguments very frequently and this could potentially be capitalised upon.

Yes I have seen this also:). XEmacs consumes about 20,000 handles after a
couple of hours.
