That doesn't seem to fit.  Why would a perfectly functional VM suddenly
develop this problem when given a slow underlying datastore (fits so far)
but then the problem *remains* when returned to a fast local datastore,
even on a different host and architecture?  And why wouldn't the other
VM's running alongside develop the same problem?

No idea, we reloaded the VM months ago.
