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

Ummm,.. Unless I've misunderstood something, you have just said that
your main driver for this was implementing concurrency but you haven't
actually tested that.

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
