I'd say this is because it was stuck in gdb on tty1. > However, after quitting gdb the system immediately suspended > successfully (and when it came back up it went into suspend again, > presumably because I had tried the suspend command above twice). As xfce4-session had segfaulted but not yet quitted (stuck in gdb) its children weren't killed and in particular the suspend order was correctly processed.
