--- Comment #1 from Remy Maucherat <re...@apache.org> ---
As a side note, without looking at the merits of the BZ, I'd like to point out
that the very common habit of doing flush and/or close at the end of a servlet
is a bad idea, it may impair better error processing and will always degrade
performance.
