If you use :fork: as the "access method" then you'll get a pipe and thus
now even better performance than a socketpair().

If you use the real repository directory (or :local:) -- i.e. completely
eliminate all the client/server B.S. -- then you'll get the maximum
possible CVS performance your machine can deliver.  For some recursive
operations the difference can be positively stunning because of the
gyrations a CVS server has to go through to handle a remote client.

I only use the real CVSROOT directory to access my local repository,
including the local copy I keep of the NetBSD repository.

(there were some problems with NetBSD's modules definitions vs. local
access for initial checkouts, but they could be easily worked around and
I think they may even have been eliminated with the recent re-org)
