In real world conditions, uniqueness of the current solution is
questionable, as often computer clocks are wrong and are adjusted on
the fly by several minutes, for example with ntpdate. This is not
recommended, but it happens. Also repositories are sometimes copied
to a different machine with a differing clock. If a repository is
under heavy load (several commits per second) under situations where
the clock might be changed into the past, PID and randomness are the
only protection against collisions.
Why not measure speed of an rcsfreeze-like solution where commit IDs
are guaranteed to be unique? I'm interested if there's really a
bottleneck.

I see. If any suasion fails, the only solution is another fork of
CVS, this seems inavoidable to me. The time spent discussing is
probably better spent programming.
