Can you clarify something for me?  You are referring to tomcat starting
child processes and not changing the uid, correct?

Another question - Can tomcat be run as another user other then root like
httpd is?

Thanks for the help.

No, tomcat provide no such features.  You can accomplish this (I think) on a
Java level (not OS-level) using the AccessController#doPriviledged approach.
(See javadoc for java.security.AccessController for more details).
