Whatever you end up with, it would be a really good idea to make it
deterministic somehow.  If the first instance starts the
sub-instances, then you could at least do the random splitting in the
first and pass it as arguments to the subs, using some known random
seed to do the random choosing.

(There shouldn't be any order issues, but when there are for some
reason, trying to recreate the bug will be a nightmare.  This has
happened in the past, and as a result I made setup-plt always sort the
directories and/or files.)
