    Fix intermittently failing test.
    
    If you fake a blocking with async write while processing a read there is
    a strong chance of a deadlock. The read will be holding a lock on the
    SocketWrapper. If the async write does not complete in-line it will
    perform a dispatch when it is ready to write and that dispatch will try
    to obtain a lock on the socket wrapper. The lock on that opbject is
    already held and a deadlock will follow.
