Already did that a long time ago.
http://www.zedshaw.com/projects/ruby_event/ and it worked OK.  Even
implemented the original SCGI Rails Runner using it as well as a telnet
processor.  Problem came from a clash with select in Ruby and libevent.

Francis solved it by using a pthread to run the select separately from
the ruby interpreter.  Something similar could be done with Ruby/Event
but most of my time is spent on Mongrel these days.

Incidentally, Ruby is apparently picking up libevent based events rather
than select for it's threads so a lot of this might be totally useless
in a year, or two, or ten, or whenever.
