remove useless synchronization in exit and quick_exit
calling exit more than once invokes undefined behavior. in some cases it's desirable to detect undefined behavior and diagnose it via a predictable crash, but the code here was silently covering up an uncommon case (exit from more than one thread) and turning a much more common case (recursive calls to exit) into a permanent hang.
