Nice, I'll get that installed...

Running off the svn trunk version of Rev I get:

rev/lib/rev/buffered_io.rb:44:in `write_nonblock': Resource temporarily
unavailable (Errno::EAGAIN)
rev/lib/rev/buffered_io.rb:44:in `write'

Which should be relatively trivial to fix.  That exception can probably be
safely swallowed, although that may not be the greatest thing from a
performance perspective.

If you try the version of Rev in trunk do you get the same thing?
