Just for fun, I told the 2.3 beta image to perform an update from the net.
It went and got all the 2.2 updates since October.  I guess this is
because the update code is the same in all images, and the expectation
is that there will only be one 'true and correct' squeak image out there
for updating.

This may become problematic if there are to be 2.3 beta updates while
2.2 is still extant, though.
