> If there is a queued callback that is processed during a writeable
> event (or read-writeable) the writeable callback, i.e. AsynchIO::writeable(),
> takes the path through
> line 536 of AsyncIO.cpp, then AsynchIOHandler::closedSocket() is called
> which deletes the AsynchIOHandler instance, the thread then goes on to
> process the callbacks in DipatchHandle, which invoke on the now deleted
> AsynchIOHandler.
> Results in cores like:
> Core was generated by `/home/gordon/qpid/cpp/build/src/.libs/lt-qpidd
> --load-module /home/gordon/qpid/'.
