Interestingly enough, when it comes to scrolling, running a GTK+ app on
OS X remote displayed to a Linux machine over 802.11b is *faster* than
running it on the local OS X display. I'm guessing context switches on
OS X are rather slow, so the chatter between the app and the X server
is slowing things down.
Certainly some of this can be improved upon in GTK+, like doing scroll
