Detailed Description

A class that wraps the operating system Critical Section API and that implements the ICriticalSection interface. The addition of the ICriticalSection interface has increased the size of this object and added a layer of indirection into the Enter() and Leave() calls. If this proves to be a performance problem then we can simply create a 'CSmallAndFastCriticalSection which doesn't inherit from the interface.
