First snippet: <> can't be interrupted because there's no way to check <> for errors. However, the signal handler does get called once it returns.

At least on my machine (Linux), it seems to be the same buffering issue...

$ perl -wMstrict -e 'alarm 2; $SIG{ALRM}=sub{
    print "Timeout reached" };<>'
^C
$ perl -wMstrict -e 'alarm 2; $SIG{ALRM}=sub{
    print "Timeout reached\n" };<>'
Timeout reached
^C
$ perl -wMstrict -e 'alarm 2; $SIG{ALRM}=sub{
    print STDERR "Timeout reached" };<>'
Timeout reached^C
