[Catalyst] Cached TT w/mod_perl issue? Or just a Toby-bug?

[Wade.Stuart at fallon.com]

mkdir /path/to/ttcache
chown apacheusr:apachegrp /path/to/ttcache
chmod 770 /path/to/ttcache
chmod g+s /path/to/ttcache

This will set the stick group bit on the cache dir and  newly created files will gain the paths groupid in the cache dir.

Delay MyApp->setup until a PerlChildInitHandler?

Or have the TT cache dir set to a *group* apache can write to and setgid
so the permissions propagate so group write sorts the problem.
