Message:

Not the bug I was looking for either, but un-botch some of the GC-state-saving
changes from a few weeks ago: save_application() is always run with the
EGC off, so make the caller pass an extra arg indicating its state as of
the time we trapped to it. Set G2_THRESHOLD global before writing image,
don't set G1_THRESHOLD twice.

Images built a few weeks ago have EGC off and misconfigured.
