.SH "Detailed Description"
.PP 
Exception thrown by __cxa_guard_acquire\&.
.PP
6\&.7[stmt\&.dcl]/4: If control re-enters the declaration (recursively) while the object 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\&.
