I described a solution about six weeks ago (with code!).  Here's the link
(or search on google yourself for SingleInstance and Muskovitz):

ython

Basically, your app creates a lockfile, and periodically touches it.  An
external app can check the timestamp on the file, and if it is too old, then
your process has hung up and could be killed/restarted.  Alternately, you
can stick your app directly in cron.  When a new instance starts up, it can
check the lock and if things are ok, then it can just kill itself.

The code works on NT and Solaris.  I haven't tried other platforms.
