That's the best reason I've seen so far :-).

It also occurs to me that one of the safe signal proposals
floating around was to make the C-level signal handler
just set a flag and have the Perl-level handler called
later. If that ever happened there would certainly be no
reason to use sigsetjmp because no perl code would ever
actually run across a signal handler border.
