[Ludovic Courtès]

in repository guile.

commit df86a2a8c8725ac6244a222d399a5b959101f621
Author: Ludovic Courtès <ludo@gnu.org>
AuthorDate: Sat Oct 1 15:28:41 2022 +0200

    Finalization thread exits when it gets EOF on its pipe.
    
    Avoids spurious "error in finalization thread: Success" messages when
    the finalization pipe gets closed.
    
    * libguile/finalizers.c (finalization_thread_proc): Return when 'data.n'
    is zero.
