Mythical small kernel images?

An important sanity check when shrinking images is the following:

1. Remove the part of major shrink that drops the source.
2. Attempt to recompile all the methods from source.

In my experience, this will reveal places in the code that reference
globals that have been removed from the system or which cannot
be defined or initialized in the shrunken image.

If you can recompile all the methods without error, then go ahead
and drop the source, do a full gc.
