This class implements a lightweight Mutex by making direct calls to the underlying implementation layer.
It doesn't perform any debugging operations.

Grabs the lightMutex if it is available.
If it is not available, blocks until it becomes available, then grabs it. In either case, the function does not return until the lightMutex is held; you should then call unlock().
This method is considered const so that you can lock and unlock const lightMutexes, mainly to allow thread-safe access to otherwise const data.

Returns true if the current thread has locked the LightMutex, false otherwise.
This method is only intended for use in debugging, hence the method name; in the LightMutexDirect case, it always returns true, since there's not a reliable way to determine this otherwise.

Releases the lightMutex.
It is an error to call this if the lightMutex was not already locked.
This method is considered const so that you can lock and unlock const lightMutexes, mainly to allow thread-safe access to otherwise const data.
