While I think the patch is good, threaded code that uses C<< open my $fh, "+>", undef >> might see some intermittent unexpected permissions on files created in other threads.

Unfortunately umask() updates the mask for the whole process and there's no thread-local variant, so I don't see a thread-safe solution.

Added to the 5.21.1 list.
