 > This function is registered as a shutdown hook, though. We don't always
 want to use the $disable_compression flag, right? Just when it's
 absolutely necessary to give instant feedback?

 I wasn't aware of that.. Seems rather useless in all honesty.. I'm sure
 there's a reason for it though.

 > From my testing (apache2 / mod_php), it does seem like the output is
 being buffered, even pulling out all of the other tricks in this patch.
 Sending a 4K block of null bytes shouldn't have any affect on the output,
 but does make the responses feel snappier.

 I'll do some testing on a stand-alone script, see what I can come up with.
 Usually a few loops, well placed sleep()'s will give you a explanation as
 to what's happening where..
