How does the --halt 2 option kill off all jobs?

[Martin d'Anjou]

Hi,

The --halt 2 documentation says:
"Kill off all jobs immediately and exit without clean up."

When I look in the source, I see in Job::should_we_halt() a call to the exit statement:

exit($job->exitstatus())

but I do not see a call that kills all the jobs.

I am confused. Does the exit() statement kill all the jobs? What code kills off all jobs when --halt 2 is specified?

Thanks,

Martin
