`coz run` produces no output if interrupted by Ctrl-C #143

It seems that coz run ... saves data only when profiling target reaches the end of main().

Some programs are designed to exit only when interrupted, or take a long time to terminate. It would be nice if Coz could deal with signals, exit(), etc, and save the data collected up to that point.

Not sure about that. It seems to periodically write to profile.coz.

The thing I saw, though, is that my server was missing latency points and I needed to run it for a long time in order to generate an actual graph. I also need to move the slider for minimum points to 2-5 points instead of 10.

Coz definitely periodically writes to profile.coz. While Coz works without progress points, it's really best to use them.
