To be really sure, you should make your servlet slow (put in a sleep
statement). Or else, you would really have to test it under high load:
if Jetty's maintaining a pool of handlers (the typical behaviour I
believe; certainly the case in my own configuration) and the servlet
executes too quickly, it can _appear_ to have just one handler.
