I do all my transcodes on my only backend (my frontends are diskless or
underpowered).

I normally set it to allow 4 jobs at a time, as commercial flagging and
media downloads don't stress my system too much.  But I can't have 4
transcodes going at a time.

I think I will just have to replace the transcode command with my script,
as you can restrict the number of concurrent transcodes.

It may be a good idea at some point to introduce a feature that allows
setting the max concurrent for each userjob.... though I am not sure how
valuable it would be?
