Detailed Description

Instances of this class acquire a given Mutex Lock when constructed and hold that lock until destruction.

The intention is to instantiate one of these on the stack at the top of some scope to be assured that C++ destruction of the object will always release the Mutex and thus avoid a host of nasty multi-threading problems in the face of exceptions, etc. Guard a section of code with a Mutex.
