Couple of questions about some perl environment variables.

The documentation for PERL_SIGNALS reads: 


  PERL_SIGNALS
              In Perls 5.8.1 and later.  If set to "unsafe" the pre-Perl-5.8.0 signals
              behaviour (immediate but unsafe) is restored.  If set to "safe" the safe (or
              deferred) signals are used.  See "Deferred Signals (Safe Signals)" in perlipc.
I wonder what happens if PERL_SIGNALS is unset or is not either of safe or unsafe.

Also, when I do a perl -V on 5.8.8, the environment variable PERL_HOME is display. Is that used at all for anything?
