I've made three changes to the current Interchange::Link which are
working out great.  The first one allows a proper 404 to be returned:

close (SOCK) or die "close: $!\n";
- return Apache2::Const::OK;
+ return Apache2::Const::NOT_FOUND

The second removes all blank lines from IC's HTML/CSS output:

while( <SOCK> ) {
- push @out, $_;
+ push @out, $_ if /\S/;

I realize that not everyone will want the blank lines removed from
their HTML/CSS output, so maybe someone can slap together a quick
variable in the module that sets it up as an option?

The third and most important prevents the frequent segmentation faults
and intermittent "Connection reset by peer" errors I had previously
been plagued with:

- $SIG{PIPE} = sub { die_page($r); };

The entire die_page sub can also be removed.  For a little more info
on this, just removing the $r->content_type and $r->print sections
from the die_page sub will prevent the seg faults, but using 'IGNORE'
as above also prevents the intermittent "Connection reset by peer"
