I'm seeing this also. It is not apparent just looking in Firebug at the "Net" requests, but both the Apache and MapServer logs show, for me, an average of 3 requests for a mouse scroll on an un-tiled layer. I'm also seeing an undesirable number of requests when the browser is resized.
I'd love it if someone told me that there was already a parameter to set a small delay before sending a request in these cases, or some other solution. But barring that, can anyone suggest where a reasonable starting point might be for adding such functionality?
