Interesting. There's no meaningful difference between v11 and v12 as far
as timeout handling goes, so I'm starting to think that that's a red
herring.
(Although, after having done some web-searching, I do wonder why timer.c
is using a manual-reset event. It looks like auto-reset would work
just as well with less code, and I found some suggestions that it might
perform better.)

it'sa major change in V12 and this is when I am starting to see the issue popup, I figured it might be another avenue
tolook into?
Hm, is JIT even enabled in your build? If so, does setting jit = 0
change anything?
