Miscellaneous tidyings:

  * Change the timeout to something more appropriate for real use.

  * Check assumptions about object types when binding the socket.  In
    particular, don't zap the socket if it's really something else.

  * In @p_request@, return a failure if the shell command returned
    nonzero.  Fix a bug in @p_get@ which incorrectly passes on a success
    code when this happens.

  * Dispose of the locked memory in client mode to avoid being
    antisocial.

  * Also in client mode, don't report closure from the server if we're
    running noninteractively.

  * Insert a missing option letter into the usage string.

  * Change to the root directory after forking in daemon mode.
