If you'd like, shoot me over your serial number and the corner-cases you don't
have answers for and I can look into it.

Hi, Layne. Glad my changes helped.
It's not surprising that there are some remaining race conditions. I'm afraid
I can't remember whether I have this particular problem or not.
My variable settings shown by upsc are below.
I think the general plan should be to run the system on the UPS for as long as
possible, then shut it down with the shortest delay possible that still allows
for a clean shutdown of your system. If these times are, say, 10 minutes and
10 seconds, then you only encounter the race if the power happens to be off for
an interval between 0:10:00 and 0:10:10, which is quite unlikely.
Actually fixing all races would be better still, but I do not have a good
enough understanding of how my UPS handles the various settings to be able to
do that.
