We definitely plan on migrating, but we're holding off right now for a 
couple of reasons:

-Tomcat 4.1 arrived in final stage very late in the test cycle for Expresso 
5, so it didn't make sense to jump ship that late in the performance cycle.

-It looks like there's a couple of issues with Taglibs, etc with Tomcat 
4.1.  We haven't tracked things down yet.

-Tomcat 4.1 requires JDK 1.3 for the shutdown hook stuff.  We haven't 
officially required JDK 1.3 yet.  [Tomcat 4.0.* will run on JDK 1.2 AFAIK]

-I don't have Tomcat 4.1 set up on my machine yet :)

Now regarding the CPU stressing... can you reproduce this under Tomcat 
4.0.* ??  I'd like to receive further information.
