If my servlet must perform some external process, rmi, sockets, etc. I
monopolize the Servlet thread until my process is done, for no good reason.
If n jobs are waiting for the external process to complete, NO THREADS are
available from the Servlet Container pool, and all http-servlet traffic
halts.
Sorry, but synchronous servlets are a hugh limitation. Obviously my example
was very simplicistic.
