Hi John,

You know what ... let's fix this problem for real. I've spent a bit of time
looking through what happens and I'm certain now that the root bit problem
only affects the active and the home context. If it were any different we
would have been crashing all the time as the original problem showed quite
nicely (it was _very_ reliable once you triggered a store into activeCtx ;-)

I've just been doing a little cleanup anyway (there is so much code
duplication between primitiveSnapshot and primitiveSnapshotEmbedded) so I'll
just add the external prim flushing to it and clean out the root bit. The
root bit in the active context can act as the trigger for doing the full
cleanup otherwise we rely on a cleanly saved image. BTW, I have checked it
and the root bit of the active context _is_ set in all Squeak images back to
1.1 ;-) so we won't have any nasty surprises.

So do we have any other cleanup we'd like to do upon image save? This is a
good time to mention it.

Cheers,
  - Andreas
