    kernel - Fix multi-threaded coredump
    
    * Recent commits to freeze threads on a coredump introduced a bug
      where threads entering a wait state could stall the coredump
      indefinitely.
    
    * Fix by counting such threads as being stopped before entering the
      wait state, allowing the coredump to proceed.  Do not try to issue
      an early signal which could disrupt the state the coredump is trying
      to save.
