Allow suspending a queue

So would it be possible to stop queue processing when e.g. during my process() function a variable gets a specific value?
I want to achieve that a process only runs until e.g. 10 jobs in a queue are done successfully in one (cron) run. So I could use a kind of counter.

Is there a workaround to suspend/stop processing a queue until the issue is fixed?

All I want to achieve is following:

If a variable has value x then don't process the queue during cron. Tried to do this with a preprocess event listener but don't know how to stop the queue processing.

I added a property to the Queue called 'suspended'. You can conditionally set this to suspended depending on your use-case. I think it's better to keep it separate from the Job result.

I added a property to the JobResult for success and failure which will allow you to break from current processing. You can separately set the queue to suspended.
