 I made some changes that I hope will help the lagging input problem
but since I can't actually make it happen here, you'll have to
try it out to see if it helps. If it doesn't actually help, its
should at least be closer to the way to go. I had to jimmy
some stuff around (made do_keepalive not static) and one or two
other things. TRY THIS OUT BEFORE INSTALLING IT MAKE SURE IT DOESN'T
KILL THE WHOLE THING.
