No, but the limit if quite higher:

max_aj_tasks                 500000

I understood that the above limit was not real because the amount of
task taken into account was really limited by max_pending_tasks_per_job
(which is low: 50).
But seems that this combo works till it reaches some high number like
750000 tasks (in my example).

I have the second as I don't want to limit the amount of running jobs
but I want to limit the amount of pending jobs that the scheuller
considers each schedd cycle.
