   1.120 +// Change Log:
   1.121 +//   6 Jun 01  
   1.122 +//      WEKEMPF Initial version.
   1.123 +//  30 May 02  WEKEMPF 
   1.124 +//      Added interface to set specific cleanup handlers.
   1.125 +//      Removed TLS slot limits from most implementations.
   1.126 +//  22 Mar 04 GlassfordM for WEKEMPF
   1.127 +//      Fixed: thread_specific_ptr::reset() doesn't check error returned
   1.128 +//          by tss::set(); tss::set() now throws if it fails.
   1.129 +//      Fixed: calling thread_specific_ptr::reset() or 
   1.130 +//          thread_specific_ptr::release() causes double-delete: once on
   1.131 +//          reset()/release() and once on ~thread_specific_ptr().
