       Exception thrown by __cxa_guard_acquire.

       C++ 2011 6.7 [stmt.dcl]/4: If control re-enters the declaration recursively while the variable is being
       initialized, the behavior is undefined.

       Since we already have a library function to handle locking, we might as well check for this situation and
       throw an exception. We use the second byte of the guard variable to remember that we're in the middle of
       an initialization.
