Just to let you know, it seems a Monitor is reentrant if you want
to take this path:

I'm aware of the difference, Mutex is being used on purpose for
performance (Monitor is about 2.5x slower).
One other limitation with the current code is that it does the
connection validation while holding the pool mutex, which means that
no other threads can checkout a connection while this connection is
being validated. That's very bad. I've modified things so the
checking is done while not holding the mutex (in addition to
precaching the SQL).
I'm just running the changes through a final set of tests, hopefully
it will be pushed within 15 minutes.
Great, specially because I tried using a Monitor instead of Mutex and
now "rails server" segfaults on JRuby 1.7 :P
