Makes me think though. Could this be a sfs synchronization problem? I
know Globus waits for a similar stamp file from a job to be visible on
the head node. But does that guarantee that all files produced by the
job will be visible and their contents up to date? Can we assume that
individual items in the set of things that can be observed from a sfs on
a node have the same ordering as their individual causes on another
node?
