Are dependent job slots guaranteed to follow their parents?

[Han Sooloo]

Imagine I have a job that does media conversion (mkvmerge) that runs a few hours.  After it is complete, I want to run another program to do some post-process cleaning (very short lived, that does a status update).

Given a job size of 4, are the jobs and their dependents guaranteed to have sequential slots?

e.g., 

[running]  Job 1

[queued]   Job 2, dependent on Job 1

[running]  Job 3

[queued]   Job 4, dependent on Job 3

Will the dependents always kick in in those sequential slots, or is there a possibility that I may end up with something like this:

e.g., if I added 2 more jobs to the queue:

Job 5

Job 7

Once Job 1 completes, am I guaranteed to have something like this?

[running]  Job 3

[queued]   Job 4, dependent on Job 3

[running]  Job 5

[queued]   Job 6, dependent on Job 5

[queued]   Job 7

[queued]   Job 8, dependent on Job 7

[finished] Job 1

[finished] Job 2, dependent on Job 1

[Lluís Batlle i Rossell]

Jobs will be run in the order of the queue, yes. Each time a run slot
frees up, the queue is searched for next task to run. Those that cannot yet run
(dependant on others to finish) are skipped.

If job 3 finishes before job 1, job 4 will run before job2.
