// Support for C++11's thread_local keyword was surprisingly spotty in compilers until very
// recently. Fortunately, thread local variables have been well supported for compilers for a while,
// but with semantics supporting only POD types, so we can use a few defines to get some amount of
// backwards compat support.
// WARNING: This only works correctly with POD types.
