implementation question #719

Just curious, when an Istanbul process exits prematurely (uncaughtException, etc), does Istanbul still collect as much coverage information as possible no matter what? Or does it only write out the info if the process exits with code 0?

this seems pertinent, because my exit code handler is not being hit, and I believe it's because istanbul's exit handler is synchronously exiting before mine gets invoked?
