I wonder if this would also be simpler if "lock" were simply declared as
a static variable, and we drop the allocation entirely. I suppose that
does create more cognitive load, though, in that it is only correct if
the function is not recursive. On the other hand, the current code makes
a reader unfamiliar with "struct lock" wonder if there is a free(lock)
missing.
