upstream load balancing.

I'm sharing processing load across 3 remote servers, and am having a
terrible time getting it balanced. 

Here's the config

	upstream backend {
		server fail_timeout=30 max_fails=3 weight=1
; # Engine 1
		server fail_timeout=30 max_fails=3 weight=1; 
# Engine 2
		server fail_timeout=30 max_fails=3 weight=1
; # Engine 3

When the server gets busy, all load seems to be put onto the final
entry, which is seeing load averages in the 70's, whereas the first 2
are below 5.

This is causing serious performance issues. How on earth can we force a
more even loading?
