Hi I like to kill things on linux gracefully where possible - meaning, if I kill a hung instance of houdini I don't usually do it with -9 cause I'd like to give Houdini a saving throw and prey that it saves a .hip to /tmp.

occasionally I find the houdini interface gets a bit hung up and steals the mouse focus while drawing a menu or something - leaving my machine unable to click on anything but I can move the mouse around.

which makes me wonder - is their a certain kill signal (SIGUSER etc) you can send to houdini that would tell it to redraw the GUI or do a bit of clean up in case it's stuck in some minor loop? if not one for that - is there a list of supported signals in general?

thx.
