This used to not be a problem, because these mutexes were the first
members of this array, meaning that we ended up trying to lock/unlock
NULL mutexes. But this isn't guaranteed to be allowed, so we were
relying on luck here.
Recently, this changed. We introduced asserts for NULL-pointers, and
changed the behavior in a way that leads to crashes in release-builds.
This means we can't rely on luck any longer.
