One point that Joe omitted to mention is that since input
filtering is a PULL API, it's entirely up to your filter
how much data to pull before returning to its upstream.
If your filter can't deal with partial data, it can block for
as long as necessary to read more.  With just a couple of Kb 
to handle it's not exactly going to be a performance hit!

Regarding the flush buckets, conceptually I'd expect they
might feature if you were handling streaming data, or
maybe multipart uploads, or some extension to the HTTP
protocol.  Maybe there's some such application- or ptotocol-
oriented filter in your chain?
