it probably needs some degree of rate limiting - just forking off
dozens of startup scripts may be counter-productive - especially if
they are I/O bound.

I don't see how to safely do all the parallelisation using scripting
tools that are available in the base system

your main driver for this was implementing concurrency but you haven't
actually tested that.
