Comment (by gvalkov):
Hi and thank you for your advice! :)
Yes I am doing something similar to binary search. But instead of
splitting in half every time I was trying to use my old memories as to
when I experienced this issue and trying to converge even faster. Now on
one hand this was also a stupid idea as it made me build and test more
revisions. On the other I figured, that if I go backward choosing
revisions that are more likely to fail, I will loose around 10-20 minutes
in testing, whereas I conclude that a revision is most likely stable if it
survives for two hours and that's a long time.

'''nbd''', can you please revise this commit?!
Now I'm going to try to reverse it manually then undo the changes from the
current master and see if this will resolve the issue. Finally I'll try to
check it more carefully and see if I can find some mistake. BTW is there
an easier way? Can I delete a commit in the middle of the path, and then
go back to the master in such a way that all next commits will be in
effect?
