        I ran across a "feature" in a recent issue of the VAX Professional
magazine that may be useful to you in tracing locks. You can get the
SHOW DEVICE command to show you the locks on a disk device. Try this -

$ DEFINE/PROCESS SHOW$DEBUG DEBUG
                            ^^^^^ this can be any string
you may want to $ SET TERM/WID=132 here...
$ SHOW DEV D

        This has given me additional output on VMS 4.7 and 5.2, I believe
the author in VAX Pro described it as a undocumented-can-go-away-at-any-time
feature.
