Mike Hommey 7f63a01cca Bug 1412717 - Make malloc_initialized atomic. r=njn
Interestingly, this turns single-instruction checks into
two-instructions checks (at least with GCC, from one cmpb to a movl
followed by a testl), but this is due to Atomic<bool> being actually
backed by a uint32_t, not by the use of atomics.
