That it doesn't work in Windows has nothing to do with safe signals,...

On no?

Try this (on a Windows system and perl 5.8.x using a cmd.exe exe console and a standard 101-key ps2-compatible keyboard configured for UK, on a Monday in November; shortly after 5.00 pm with a tail wind and a little good luck...) 

C:\test>set PERL_SIGNALS=safe

C:\test>perl -wle"$SIG{INT}=sub{exit}; sleep 100"
Terminating on signal SIGBREAK(21)

C:\test>set PERL_SIGNALS=unsafe

C:\test>perl -wle"$SIG{INT}=sub{exit}; sleep 100"

In the first case, ^C has no effect, hence the need for ^break (SIGBREAK).

However, the second example (with set PERL_SIGNALS=unsafe) it responds to ^C immediately.
