It's not exactly a high-level event-driven architecture, but we do
have Kernel#select, which makes the same sort of non-blocking,
callback-driven event model possible. The Medusa library adopted by
the Python/Zope folks might not be a bad place to start for a simple
example of using the select() call as a sort of "event kernel".

There's also Twisted, and on the Perl side, POE, to mine for design ideas.

I also recall some discussion on ruby-talk of someone trying to write
a Ruby extension to wrap libevent, but IIRC, the Ruby threading model
blocked (pun indended) the whole deal.
