Erm... why would we be unable to read the data?

I have the exact same CGI.  If I have it output, for example, 6k of data
there is never a content-length.  If I have it output, for example, 10k of 
data, there is.

Sure, once you go _above_ 32k (erm.. 4*AP_MIN_BYTES_TO_WRITE I think) 
then it won't buffer.  But that isn't the issue.  The _smaller_ response
isn't getting the content-length added.  The content length filter is
calling ap_set_content_length with the right value, but it never 
makes it to the client... don't know what is going on there.
