This wouldn't do anything in my case because I'm appending points from
within an expat callback (so my method that calls append_point never
has access to more than one point at a time anyway).

You mean with some kind of threshold, so that a redraw would only
happen x seconds after points have stopped being added? I could get
behind this, but it would need some kind of override method you could
call to force a redraw. The way my GPX parser is structured it pulses
a GtkProgressbar every 0.2 seconds, and it would be nice if the loaded
points would be visible to the user at this time, so that they can see
that something is actually happening (there's really nothing worse
than a slow-loading file just sitting there looking like the app is
hung).
