have a look at what Eric recently added to the api:
=item $c->fileno( [$direction] )
Returns the client file descriptor. If $direction is 0, the input fd
is returned. If $direction is not null or ommitted, the output fd is
returned.
This can be used to detect client disconnect without doing any I/O,
e.g. using IO::Select.

hmm, I thought we were done with SIGPIPE, the patch below will re-enable
auto-calling of Apache::SIG->set
