Thanks Joe!

That helps a bit , but creates a new problem:

I think what happens is this:
	without discard_request_body :
		web application immediately detects overlimit , does a connection  
reset
			curl still fetches the page
			safari spins forever
			firefox displays a connection reset error
	with discard_request_body :
		web application detects overlimit, but it reads a lot more of the  
body than it should
		this doesn't manifest itself outright on small files ( 1mb ), but  
when I posted the FreeBSD 6.2 disc image ( 670mb ) , it was clear  
that the webapp was hanging while the client still sent data.

is there a way to guage how much of a the body has been read by  
apache ?  the UPLOAD_HOOK doesn't seem to be stable and hook_data is  
unsupported .  i couldn't find anything in the core mp api.

by the time uploads take alone, i do know that something odd is going  
on, and more than 200k is being read:
	<1s to display error: Content-Length header (546500) exceeds  
configured max_body limit (200000)
	3s to display error:   Content-Length header (72727196) exceeds  
configured max_body limit (200000)
	6s to display error:   Content-Length header (670108355) exceeds  
configured max_body limit (200000)
