Probably I misleadingly draw a connection from the
Mailscanner-driven perl processes I see on some machines to the
usage you are actually talking about. Those contribute to a decent
utilization of ressources, but I admit their job is totally different.

Sounds interesting.

Hm, this looks like you know what you're talking about. I once found
out that perl is too heavy for the job, but that was perl 4.x, a
different task and of course no embedded perl. So I should probably
better keep my prejudices in the future if not throwing them away ;)
