Errr?  I can do that??? Let's see....
Just tried (startx &; logout).  That works pretty well.  I guess it 
never occurred to me. Though had it... I would've thought I'd have had 
to nohup it.

Works great!  Thanks!

Actually, I did try lock (though not with the 'p' option).  Somehow the
'p' eluded me in the enormous 10 sentence man page :}.  So when I tried
it... it prompted me for a password.  And I did not like that.  So I
just now tried it again with -np... and although it does not prompt for
the password to use for unlocking... it behaves the same as vlock does.
  It seems to get some input from somewhere and constantly, repeatedly
accepts a phantom key, says its wrong and then prompts, accepts a
phantom key.... on and on.  So unfortunately this does not work (for
me).  Do you get different behavior?  I used 'startx &; lock -np' to test.
