Lets see if I understand...

You can check ns_conn contentlength in advance and
decide to get all the content or to discard it (because too large).
You can use ns_conn setmaxinput to some large(r) value and then
call ns_queryget.
The ns_queryget will call Ns_ConnContent and this is now clever
to either return the content from memory (if < maxreadahead)
or do more complex stuff by mapping file and sinking all the
content in a memmaped file. The returned byte array for futher
parsing would be just from the mmaped file. The callers of the
Ns_ConnContent will not see the difference.

Stephen, did I got it right?
