ns_job manages a thread pool and a set of named "queues". Queues have a max number of threads and when the current number of running thread reaches "max" then jobs are queued. New threads are created when there are less than maxthread number of idle threads. OPTIONS

If maxthreads is not specified, then the default of 4 is used. queue queue ?-detached? queueId script Add a new job to the queue. If there are less than maxthreads current running then the job will be started. If there are maxthreads currently running then this new job will be queued. If detached is true, then the job will be cleaned up when it completes; no wait will be necessary. The new job's ID is returned. wait wait ?-timeout seconds:microseconds? queueId jobId Wait for the specified queued or running job to finish. wait returns the results of the script. An error is thrown if the specified timeout period is reached. waitany waitany ?-timeout seconds:microseconds? queueId Wait for any job on the queue complete.
