4.1 and vms on same disk anyone?

We are about to try a variation on the same theme: we're going to
attempt to put 4.1c in a large contiguous file on the VMS disk.  I
expect that this will prevent VMS from munging our filesystem, as it
certainly shouldn't mung user's files when the diagnostics run.

Now, if we can just compress the VMS disk to get a nice, big contiguous
file...  Anybody got any clues there?
