If gconf cannot put a lock in $HOME, then the desktop is not started.

This is a problem when the $HOME directory is NFS mounted from a different
client which does not run statd/lockd.  The lock daemons have had a number
of security and other issues, so running them is not necessarily desired;
even if run, version issues frequently prevent them from working correctly.

An option to Gnome to avoid locking (assuming only one login/user at a
time) would solve the problem.

Currently we cannot use the more recent release (through RedHat) of Gnome,
as it will refuse to lay out a (single) desktop.
