Use a transaction when enqueuing a job to ensure atomicity #222

There are cases when the scheduler receives a SIGKILL between the zrem and zadd from enqueue_job(). This would, in turn, lead to occasional unscheduling of the repeatable jobs.

The solution I propose is to put everything in an atomic transaction and thus assure atomicity.
