You don't need to play this game.  If you set
desktop-load-locked-desktop to t, Emacs will unconditionally load the
desktop even if locked, no questions asked.  Its effect is the same as
not having the lock at all, when the process which locked the desktop
no longer runs.

That's because you cannot, not without changing desktop.el.  Maybe you
can do that by customizing desktop-base-lock-name to "NUL", but I
didn't test that and am not sure it will work.  The customization of
desktop-load-locked-desktop I suggested above will have the same
effect, so I see no reason for you to try something that is
unsupported and untested instead.

Then I think customizing desktop-load-locked-desktop to t is exactly
for your situation.  Does it cause any further problems?  If not, why
not use it?

The lock was introduced in Emacs 22.2, quite some time ago.  It isn't
a new feature.
