This revision is now accepted and ready to land.

This will be nice to prevent bugs in the future. Should it be behind `#ifndef NDEBUG` though? Presumably if assertions are disabled then this bug would be expected to be undefined behavior and avoid the overhead of the thread local variable, is that right?
