Detailed Description

Class for creating a Mutex for a statically allocated critical section of data.

---

When an object is created in static memory, the order of startup and shutdown is indeterminate in a cross platform way. To avoid an accidental call to this class before it's constructed or after it's destructed, this class will test a flag to determine if it's out of sequence and if so, the lock() and unlock() functions will perform no action. Since C++'s startup and shutdown sequence is performed on a single thread, this is a safe method to ensure that unknown startup/shutdown sequences won't accidentally thread lock.
