Maybe it uses one of the semaphore implementations that consume a
file descriptor per semaphore?

I think that d20703805 was insanely optimistic to think that a
tiny value of max_files_per_process would work the same everywhere.
I'd actually recommend just dropping that test, as I do not think
it's possible to make it portable and reliable.  Even if it could
be fixed, I doubt it would ever find any actual bug to justify
the sweat it would take to maintain it.
