Yes, with too little entropy to be useful, and too much for being
harmless :)

As far as I understand (the implementation is Jaroslav's, I only made
some patches to the random number part) one would need to rewrite the
core implementation, which is based on a first-come first-served
criterion. To gain reproducibility one would need to do a static
scheduling beforhand, and assign a given list of jobs to a given process
in a deterministic way. I would definitely find a use for something
like that, as I use monte Carlo myself. Moreover, that would be a
scheme simpler to implement with respect to the current one.
