Detailed Description
Generic non-recursive exclusive lock class.
This class also impliments the exclusive_lock protocol. In addition, an interface is offered to support dynamically managed mutexes which are internally pooled. These can be used to protect and serialize arbitrary access to memory and objects on demand. This offers an advantage over embedding mutexes to serialize access to individual objects since the maximum number of mutexes will never be greater than the number of actually running threads rather than the number of objects being potentially protected. The ability to hash the pointer address into an indexed table further optimizes access by reducing the chance for collisions on the primary index mutex.
