Yes, that is the low-hanging fruit I found. ;) Just adding:

  $jobs = @scripts if @scripts < $jobs;

cuts the time to run all scripts individually from ~4s to ~1.7s.

Removing the threading entirely goes to ~1.1s. I hadn't tried that until
now, but it is probably worth doing for the case of $jobs == 1.
