because you are only having one machine do the disk/NFS access, so there are no
race conditions with the creation of locks files (yes I still think there is a
race ... I have seen the problem when all machines were running the same
version and patches of solaris with ~8 developers).  Apparently AFS may be a
bit better at handling the locks, but try looking for threads on AFS as well,
these issues were discussed there and some of my errors in thinking were
corrected by Larry there.

I'd crawl over an acre of 'Visual This++' and 'Integrated Development
That' to get to gcc, Emacs, and gdb.  Thank you.
