Subject: 24.3.50; desktop-read doesn't claim the unused lock

When the previous session crashes or freezes, and .emacs.desktop.lock
contains the PID of the previous process, then `desktop-read' asks

  Warning: desktop file appears to be in use by PID...
  Using it may cause conflicts.  Use it anyway? (y or n)  y

But answering `y' doesn't claim the ownership of the lock,
desktop-owner is still an old nonexistent process, and thus
auto-saving doesn't save the desktop.

Maybe `desktop-read' should call `desktop-claim-lock' in this case?
