  I've put together some code for this -- I hacked up rcorder to
output sets of scripts which can be run simultaneously, had rc.subr
run them in the background, and had /etc/rc wait after each group.
  Much to my surprise, it didn't help -- in fact, it resulted in a
5% slowdown (on my single processor, HTT-enabled system).
