& @lock ownership
 
  OWNERSHIP LOCKS:
 
  Key: $<object>
 
  You pass an ownership lock if you have the same owner as <object>.
 
  Examples:
    > @lock mystuff=$me
    Only objects you own may use the mystuff exit.
 
    > @lock/page me = !$*TinyJerk
    Neither TinyJerk nor any of his objects may page you.
 
  See also: @lock normal.
