svn and trac on apache

[ephigenie]

For the sake of it :

I'll recommend using trac with fastcgi

1) it can be run with the same user as the other scripts in your domain
2) it doesn't bloat apache that much as mod_python does (trac uses clearsilve template engine which uses up to 140M of Ram. If you're running that on apache/mpm_worker than each child (child not thread) will take the same amount since something in the code makes SHM unavailable between these processes.
Fastcgi / trac uses SHM area as such its ~140 (1x)
