No, it may be, but I have no personal experience with it, nor in
fact, even looked to see if it is safe :)

But then I run an Apache with svn, php, mod_python, mod_perl, etc all
in the same process, so the prefork is really the only safe way for
me to run.

If you have a dedicated svn box with nothing else on it so you could
safely run the worker mpm, then it's probably not that loaded anyway.

If speed is a real issue, then I would think moving to svnserve is
what you would do.
