The ServerHandlerManager is in charge of starting all the servers (it 
reads the server.props, finds the name and the class to start. It should 
be possible to start a tomcat engine from there. Also this class is able 
(on Unix systems) to start the server at root, and change the 
uid/gid/chroot for security reason (hence the "strange" way to do the 
startup).

Ah if there is a need to translate request object, it may also have a 
cost, but it's probably doable, with tricks if the streams are not the 
same (you can take a look at the servlet wrapper to see how fun it was to 
mix input and output streams :) ).

Be it Jetty or Tomcat, any "better" implementation of the servlet stuff is 
welcomed :)
