Class Description

                                                                      
 TSemaphore                                                           
                                                                      
 This class implements a counting semaphore. Use a semaphore          
 to synchronize threads.                                              
                                                                      

 Create counting semaphore.

 If semaphore value is > 0 then decrement it and carry on. If it's
 already 0 then block.

 If semaphore value is > 0 then decrement it and return 0. If it's
 already 0 then return 1.

 If any threads are blocked in Wait(), wake one of them up. Otherwise
 increment the value of the semaphore.
