exit(0) - done, permanently
exit(1) - done until restart interval
exit(other) - crash
and there's no way to obtain the "restart immediately" behavior?
I think this is an improvement, but it probably depends on what
you think the use-cases are for bgworkers. I can definitely see
that there is a need for a bgworker to be just plain done, though.
