Comment:

 boost 1.46.1, WinXP, MS VC2005

 shared_memory_object::remove still returns false on success in about 1 of
 30 calls.
 Label_A message below pops up.

 {{{
 string const name = m_ShMem->get_name();
 m_TraceQueue->removeUser();  m_TraceQueue->~SharedMemTraceQueue();
 delete m_ShRegion;           delete m_ShMem;
 for (bool toDelete = true; toDelete; ) {
     toDelete =
 !boost::interprocess::shared_memory_object::remove(name.c_str());
     if (toDelete) {
         struct stat buff;    string fullName;
         boost::interprocess::detail::tmp_filename(name.c_str(), fullName);
         toDelete = (0 == stat(fullName.c_str(), &buff));
         if (toDelete)
             cerr << "Still trying to remove " << name << endl; //sleep...
         else
             cerr << name << " not existing anymore. Skip\n"; // Label_A
     }
 }
 }}}
