To all you folks who are struggling with signals: Good luck! and Thanks!
(Saves the rest of us a lot of work...)
Oh by the way, whatever you do for SIGINT/SIGQUIT, make sure the "right thing"
also happens for SIGHUP (carrier dropping on a serial port) or dialin shells
(and their children) won't get killed properly, and there will be a security
hole on dialin lines. (Also, SIGHUP has to be "catchable", so editors can
save their files when the line drops.)

If anyone's working on removing the assumptions the terminal driver makes about where to send signals (LOW_USER + 1 + proc) I did this a while back. The method I used required mods the the MM (since it dealt with process groups), the FS (to implement control terminals), and the TTY driver (since it's the one that sends the signals). These were posted several months ago under the title "Patches to fix control terminals" (or something similar to that) from the userid bishop@ecsvax.UUCP. alan
