        Don't use gdm_debug() from signal handlers - the message
        formatting and the syslog() both involve malloc() which
        isn't safe in signal handlers. Fixes random lockups with
        debugging enabled.

        * daemon/server.c:
        (gdm_server_usr1_handler),
        (gdm_server_child_handler): don't use gdm_debug() here.

        * daemon/slave.c:
        (gdm_slave_usr2_handler),
        (gdm_slave_child_handler): or here.
