Walden, I can categorically state that servlets are not synchronized by
default, and that multiple threads execute the same servlet.  If you'd like
to prove it to yourself, you can simply try using some local variables in
your servlet and watch them get stepped on (this is a painful way to learn,
but quite informative).

Now, if you don't have enough threads available, then certainly you will
begin to backup, but that's not usually the case.  Usually, the thread is
only in use for the time of the request and then released once the response
is returned to the user.  However, if you use the persistent connection
capability of the newer HTTP specification, it will lock a thread (and a
socket, IIRC) for the duration of the conversation, and this can quickly
degrade your machine.
