There's no benefit from mod_perl that isn't also had via one of the
FastCGI implementations or a lighter weight server (Starman, for
instance) behind an Apache reverse proxy.  And there *are* downsides to
mod_perl as well as having to run multiple Apache instances.  So,
possible, but not close to worth it.  :)
