Makes sense. Here is the corrected patch v2.

How exactly we reach this code patch is a good question. I tried to
understand the exact conditions by using my steps to reproduce and an
ancient debugging technique with sleep(), elog() and `watch` - see
trick.txt. Unfortunately I was not able to reproduce it again nor
under Valgrind nor without it. I guess it means that either I did
something differently before or the right conditions are met under
rare circumstances.
