For Trac, due to limitations in Python wrappers for subversion, you
must use:
WSGIApplicationGroup %{GLOBAL}
So, if using subversion you don't have a choice and if need separation
must use daemon process groups instead.

Delete WSGIReloadMechanism directive. This is default for mod_wsgi 2.X
and will not even have choice in mod_wsgi 3.X. You should not be using
mod_wsgi 1.X.

Use:
WSGIApplicationGroup %{GLOBAL}
to avoid subversion issues.

This one will run in embedded mode. Especially if using prefork MPM,
bad idea to use embedded mode. Better off delegating this one to its
own daemon process group as well.
