When that was written, we wanted to be sure we were in the same RPM
transaction doing the safe upgrade.  I personally always hated the
temp file, but it was all we could come up with at the time, and to
make it somewhat more difficult to be fooled, we used both the pid and
the lstart time of the parent.  That it fails on SLES9 is a new bug,
so we'll have to come up with something else. I'm open to advice.

(pid space isn't all that large, hence wanting to add something more
likely to be unique: pid + lstart was thought to have the right property).

Thanks,
Matt
