What do you mean by 'run multiple Tomcat workers' ?
If you launch multiple instance of tomcat, each will run
on it's own JVM.

If you're using mod_rewrite, you didn't have to use mod_jk.
Just redirect to the tomcat and it's native http protocol.
IMHO, having a thread-unsafe servlet and SingleThreadModel,
and playing with many JVM will be a nigthmare for you in
production. Better try to fix the servlet.......
There is so many mecanism in java to avoid concurrency....
