Webware itself seems totally stable.  However, you are always at the mercy
of whatever C-coded extension libraries you are using.  One bug there and
either your whole process goes down, or your threads get wedged one at a
time until there are no threads left available to handle requests.  That's
the advantage of a multi-process model -- an unstable extension library is
much less harmful.

But if Webware were to use a multi-process model, you would lose the ability
to efficiently cache SQL results in memory for all servlets to share.  I
would have a hard time giving that up.
