    In most cases reboot failed on my system.  After "Restarting system.", UML
    exited without further messages.  I found an SIGIO being processed by
    sig_handler() resp.  sig_handler_common_skas().  Don't know, why this exits,
    maybe the context is no longer valid at this time.  So, I changed the sequence
    in the reboot part of main() to stop the timers and disable the fds before
    unblocking the signals.  Since this wasn't enough, I also added
    set_handler(SIGXXX, SIG_IGN) calls to disable_timer() and
    deactivate_all_fds().  Now reboot works fine in SKAS and it still works in TT.
