#2918: shared_mutex for win32 size optimization
--------------------------+-------------------------------------------------
 Reporter:  andysem       |       Owner:  anthonyw    
     Type:  Patches       |      Status:  new         
Milestone:  Boost 1.39.0  |   Component:  thread      
  Version:  Boost 1.38.0  |    Severity:  Optimization
 Keywords:  shared_mutex  |  
--------------------------+-------------------------------------------------
 The shared_mutex for win32 API contains references to the semaphore
 handles in the internal array. While this allows to make the
 implementation code cleaner, it also adds 33% of size overhead for the
 mutex object (8 bytes on x86, 16 bytes on x64).

 Please find the attached patch that removes the references and compacts
 the mutex while moderately affecting the code readability.
