The only way I can think of is to regularly output something inside the CGI,
and thus make it fail in the very moment the pipe is closed.

But I didn't try that myself - and if it doesn't work I don't think you
stand a chance, because that's the way sockets work - there is no
signalization beyond that, and even if it were it's not propagated across
CGI.
