1. Is there any way to cancel a running Job and prevent it from being re-scheduled
when it finishes, which it will do if #schedule() has been called on it while it is
running?
2. Related: Is there any way to determine whether a Job has a pending #schedule()
call, i.e. it will be re-scheduled when it is finished with its current execution?
The problem I have: I have a Job that executes repeatedly. I would like to cancel
and re-schedule it whenever certain events occur. It seems like it is possible for
the Job to be re-scheduled between my calls to #cancel() and #schedule(), meaning
that my #schedule() call will cause the Job to be run yet one extra time, which
I don't really want. Any ideas?
Thanks.

I have a function that deals with the first and might suggest a solution
to the second:
public void stopNow() {
if (getState() == WAITING || getState() == RUNNING) {
cancel();
}
if (getState() == SLEEPING) {
wakeUp();
cancel();
}
}
