Here's a suggestion. It works best if PERL_SIGNALS is renamed to
PERL_UNSAFE_ISGNALS:

To set all signals to pre-5.8.0 behavior use the ALL value (or
__ALL__, if there are systems where ALL is a valid signal name, or
another alternative would be "1"):

	PERL_UNSAFE_SIGNALS=ALL

For a restricted list of signals use a space separated value:

	PERL_UNSAFE_SIGNALS="USR1 ALRM"
