For all bugs like this, I suspect hitting the race condition will require
running the test case for months or years. That's part of why bugs like this
are so frustrating: imagine your mission-critical system crashing just a couple
times a year and the crash not being reproducible. It might be easier to hit
the race with some extreme usage of scheduling priorities to prevent the
unlocking thread from executing for a long time.
