Also doing alt-f# and control-w and such when using vnc is getting VERY
irretating, since vinegra takes control-w to mean close current
connection, while I want it sent through to delete work, or do other
things.  xvnc4viewer doesn't grab focus properly, and won't sent alt+f#
through, so my window manager still sees those.  All these work fine
with running it through a forwarded X connection, except the 6336 change
made that unusable.  VNC mode is a pain in the ass, although very
efficient protocol wise.
