Try the latest code which implements this.  _You_ can get it now
(developer's CVS).  It won't appear on the anon CVS server until
tomorrow though.

We were also calling create_image() from other places, and I haven't
messed with refresh_image(), which does only the layers above the
map drawing.

Now we only call create_image() from new_image(), which gets called
by UpdateTime if request_new_image has been set.  It looks like we
only call refresh_image() from UpdateTime() as well, and only if
certain conditions occur.

It was working for me, using a Serial GPS interface, monday night
for about 6.5 hours straight while house-hunting.  What type of
interface are you using?
