It's a little tricky, and in any case the better solution is to ensure
that the semantics are the same with or without the saved image.

If it turns out that the time penalty for library(foo) with no saved
image is very large when foo contains class/method code, we could give a
warning at INSTALL time if a saved image is not created.  Or perhaps
make saved images the default?
