cluster/nufa not consistent across nodes running 2.0.0rc1

[john at physics.unlv.edu (John Kilburg)]

Running cluster/nufa on a 5 node cluster running version 2.0.0rc1 we
noticed that not all files are visible on two of the nodes.

So I switched from rc1 to rc4 and from cluster/nufa to
cluster/distribute (changing two things at once keeps it challenging to
debug :).

After the restart all of the files appear to be available on all nodes
and we avoid the cluster/nufa scheduling problem.
