I know some add-ons to Firefox which alter page content cause delays while
they buffer the entire thing re-write it before display.

IE6 also has something which can cause it to act the same, holding a page
HTML from display until all objects have been received (preventing display
if some fail!).

In Squid the chunked decoder needs to buffer the reply to decode it for
clients, and for some very large objects can be delayed. Mostly seen with
large images such as google maps/earth/streetview. But may also occur if
the server is slow and HTML page very long.
