It doesn't really make a difference. Even if you do only one read during 
the read event, it is possible to only send a portion of the chunk 
header, causing the ChunkedInputBuffer to block if its previous chunk 
was fully read (or if it is the first chunk). The only realistic 
solution is to add a system property forbidding reads during parsing of 
the chunk header, as I don't think it's a very reasonable situation.

Ok. I was ready to tag tomorrow evening before starting on the timeout 
feature for APR, but I can wait more if you have changes to do 
(otherwise, I don't think anyone is going to really test since it's the 
WE). I can tag again if there's a horrible bug.
