   I've never played with mod_perl2.  Yes, the docs seems to
   indicate this would work.  

   Continuing to display my ignorance :-) I'd think this means
   that *each* apache child would then have a perl interpreter
   and namespace for each RT instance.  So if you have 10 RT
   instances, one of which is really busy, you might spawn
   20 apache children, each of which has 10 perl interpreters.
   As opposed to fcgi, where you could have 20 fcgi processes
   for the busy RT instance, and 1 each for the other 9
   RT instances, therefore 29 fcgi/perl interpreters in memory,
   as opposed to 200. Although a lot would be paged out.
