I suggested this very same thing about two months ago. I didn't get any responses about it being possible, but you would think that it would be. I'm not sure you would want to "crash" the system, but the pricipals (writing memory to swap) would be similar. Somehow a "dump" would have to be interpreted as a clean vs. crash core. The reason I would like this functionality is for a multi-os system I use that I could quickly change OSes yet still have my X seesion up with all my terminal windows open with command history, browser, etc. I suspect there are other applications as well. The only suggestion was to use VMware to run other OSes from BSD, but that's not quite what I was after. Chris
