What about a plugin that does both ?
Do you think that adding some "watchdog" function to perfparsed would be =
a good idea ? I
mean adding some "touch /var/lock/some.perparse.lock" feature in the main=
 loop. Your
plugin could test that file mtime :)

When perfparsed breaks, if you can find the reason, tell us, and we'll tr=
y to find a way
to make perfparsed do something else than break.
