No file locking complicates running some programs from cpu

gcloud and gsutil require file locking on configuration stored in ~/.gsutil/... If using cpu to provide ~/* to the remote node, this would appear to fail with: function not implemented

This should be a duplicate of #205 where I added some more details, WDYT?

Yes, probably this is a duplicate based on #205.
