That's not all.
If you set $SIG{__DIE__} so that it prints out any error message in a
customized way, e.g. for fatals-to-browser in a CGI context. Then you
you do an eval() call, to do some error trapping. If it terminates with
an error, instead of just setting $@ and silently abort, perl will also
call this handler!
