I like libevent and all, but I don't think Twisted's use of libevent is a particularly big win for Twisted.
Again, this is apocryphal, but I remember someone trying to wrap Ruby around libevent and failing; I remember there being a reason this had to be done bespoke. And having fallen into this particular NIH trap many times before: there's just not a whole lot to a simple socket I/O loop.
What's been your experience with JRuby/EventMachine?
Zed shaw tried to make libevent work with Ruby, but this was when we had Ruby 1.8.5 and there were problems with Ruby interpreter that prevented this (around threading IIRC).
