System designers have to make choices. You can't run LSF and PBS at
the same time on a single cluster and have them transparently and
dynamically share resources.  If you wanted to run a different batch
system on my production cluster at FSL, then the reliability features
I've integrated with PBS wouldn't work anymore.

You can only be so flexible if you want to deliver innovative
features. The Scyld guys have made a reasonable choice.
