This might be quite difficult to reproduce in a test because on my machine this
happened at 50 forks but on David's machine at 100 forks, so someone might have
a machine where 1000 forks are required and when we do 1000 forks on lower
specced machine it might totally freeze. I cannot come up currently with any
way to test this specific case in a consistent way.

Also while finding ways to test this online I came across this and there
doesn't seem to be any way we could use currently with Koha's testing
framework:
<https://softwareengineering.stackexchange.com/questions/196105/testing-multi-threaded-race-conditions>.
I don't know much about fuzzing and stuff so that could potentially something
to look into, and stress testing Koha with 1000+ clients connecting
simultaneously.
