Linux 2.3.50?  Huh?  Assuming that's 3.2.50.  Anyways, user-visible
memory usage is only dependent on glibc version.

No, pool_size for XEpollThreadPool is the number of worker threads
capable of dispatching the application.  It can hold many more clients.

Yes, mall works, too, and you can tune a running app with some of the
knobs.  However, for arena settings, I think they must be set early on
(before many threads are spawned) to be effective.  So environment
variables (set before starting Ruby) are probably the best bet, since
Ruby (MRI) spawns a background timer thread right away.
