The SbRWMutex is a mutex that i sused to grant both read and write access to the data it protects. Multiple threads can have read locks on the data at once, but only one write-lock can be given out and not while a thread has a read lock on the data.
The policy on granting read locks to threads when a thread is waiting for the write lock is something that should be configurable at construction time but which isn't at the moment.

This method blocks the calling thread until it gains write lock status on the SbRWMutex object.

This method tries to gain write lock status on the SbRWMutex. TRUE is returned if it was successful, FALSE otherwise. This is a non-blocking operation.

This method is used for unlocking the calling thread's write lock.
