This shounds like you're talking about thread *termination*, which indeed is 
not safe. IIUC, then a future thread cancellation feature in boost::thread 
works with exceptions which are thrown from lock/wait functions. So, a thread 
cannot be cancelled while it is busy allocating memory inside malloc/new.
