The biggest trouble with lockfiles is to find some heuristics for
deciding when they're stale. Imagine you're left with an existing
lockfile and no sitecopy is running (eg the power went off) - you're
never updating your site again. Ok you could print a msg asking the user
to remove it...

I found I used sitecopy from a wrapper script anyway, to supply the
arguments needed for a site, and to log its activity. From there it
would be easy to make use of the program called lockfile from the
procmail package.
