cvs screen scrolls very slowly in v-split mode

[Hermann Gausterer]

hi :-)

i tried the yesterday cvs version of screen for getting
the new features :-) great work!!

i compared the old version (default of ubuntu 7.04)
(screen 4.00.03 (FAU) 23-Oct-06) with the yesterdays version 
(4.00.03jw4 (FAU) 23-Oct-06) in vertical split mode,
it scrolls so slowly, that you can nearly read the output
of a "ps xaf" line for line; even in VIM you can see the
cursor jumping; after some investigation, it looks like
the new version is producing a lot more traffic; because
i am using it mainly over ssh, i did a snif of a full
"ps xaf" with the new and the old version; the old version
needs 107 packets, the new 2618 packets; thats a lot more!

if i use only the old (horizontal) split mode, everything
is fast as expected; is this a known problem?
