- By doing i/o to a new hft (the cat to /dev/hft/1), you cause the kernel
- to ask the current (i.e. hung X server) to give up control - I think
- the mechanism is a signal (perhaps SIGRETRACT). If this signal is
- not responded to within a specified interval (perhaps 30-60 secs), then
- the display is summarily grabbed and handed to the new hft.
-
- Of course, the real question is why the X server got hung in the
- first place.
