I took that limit from the --number-processes
parameter. But that is a bit different than the number of jobs here. So I don't have anything against making the limit larger. I think we should have some limit, to save the user from themselves doing something ridiculous here. And the question is at which point more threads will not make this faster.

Tile based CPU bound work like this will generally parallelize until the CPU is saturated, with as many threads as there are hardware threads. The OSMF render servers have 112 threads, and they're moderate as servers go.
