Comment (by anonymous):

 As said, the win32 implementation has this:

 {{{
   namespace boost {
     namespace detail {

       BOOST_THREAD_DECL void __cdecl on_process_enter()
       {}

       BOOST_THREAD_DECL void __cdecl on_thread_enter()
       {}

       BOOST_THREAD_DECL void __cdecl on_process_exit()
       {
         boost::cleanup_tls_key();
       }

       BOOST_THREAD_DECL void __cdecl on_thread_exit()
       {
         ...
       }

     }
   }
 }}}

 These functions are then somehow added into the PE image destructor
 sections (tss_dll.cpp and tss_pe.cpp). This was also buggy in some boost
 versions and messed up MFC cleanup (which also a tls handle leak) so we
 just disabled that and call the on_process_exit() function manually.
