Comment (by viboes):

 I don't understand how the error is in


 {{{
 45                  i->second->unlock();
 }}}


 after the patch. The patch ensure that there are no elements in notify and
 so the following code shouldn't crash.


 {{{
     thread_data_base::~thread_data_base()
     {
         for (notify_list_t::iterator i = notify.begin(), e = notify.end();
                 i != e; ++i)
         {
             i->second->unlock();
             i->first->notify_all();
         }
         for (async_states_t::iterator i = async_states_.begin(), e =
 async_states_.end();
                 i != e; ++i)
         {
             (*i)->make_ready();
         }
     }
 }}}


 Please could you comment the code inside this function in
 src/win32/thread.cpp?
