No, I'm not guessing, this is an observation. We had a discussion about this
issue some months ago and Thomas de Groot observed the same. Look at

Very mysterious, first time a link to the POV-newsgroups doesn't work. It was at
povray.beta-test, "Resuming renders in 3.7 RC6 is confusing at best, broken at
worst" by Chaanakya at 21 Aug 2012 19:30:00.

Best regards,
Michael

The very first link worked perfectly fine for me (I haven't tested the 
others).

Did anyone ever file a bug report on this issue?

I don't recall seeing one. It's definitely something we need to look
at as I can't see us releasing 3.7 if it's faulty.

When a Windows update need to reboot, it ask you and will wait untill 
you sellect "Restart now" or "Ask again in...".
There have been a few times when I had that dialog open for a few days.
Any way, I prefer the setting that download the updated, then ask to 
install them.

One possibility would be to check at some point if some area are still 
blank, or have only radiosity pretrace data. It could be done on a 
resume or after the trace is otherwise finished.
Another way, would be to keep a per-tread last rendered block and not 
just a last rendered block.

I've definitely had it go to sleep on me, with a render in progress. Had to turn
the sleep mode off completely, to prevent this (which is probably not good for
the ol' hard drive.) I always thought it was just an odd Windows bug. (But if I
recall correctly, POV-Ray was the only application this happened with...although
it's also the only app I use that churns through work for hours on end.) So
adding a fix to POV-Ray is a great idea!

YMMV, but I happened more than once to get an XP rebooted without
consent because it was updated and unattended long enough (coffee
break... oh, login again!)
