One problem with that is if you send a process a string of signals that cause a core dump and then kill. In the old case you would just get a full core dump on the first signal and be done. With your change it would process the second signal too and stop the dumping and you get none or a partial core dump. That might well break existing setups.

Probably, my patch is not usable as is anyways because it would need to save the mask somewhere so that the ELF dumper can build the correct mask. Your version would at least avoid that problem.
