I see where you're going - and I like the queue idea - but wouldn't it be better for that second function to just monitor the queue - and pull data off the queue that is problematic? Of course 'monitoring' is not exactly the same as 'processing' the actual data - so you'd have to know exactly what to pull off. Which would be just as easy to add that to the original process and just delete the unwanted data as you pull it out of the queue anyway. In either event, you seem fairly bright - I probably don't follow. The main thing is that I believe system processes do monitor those other processes and restart them if they crash - I think the problem comes in when data overflows or buffers spill out into other processes memory areas. ( I am not a programmer, although I do try to be for fun ).
