Don't worry, I'm no longer advocating rebasing everything over and
over again. However, I think that we must re-rebase a DLL during a
re-install for the following reasons:
o determine whether or not the image size has changed (and act
o actually rebase the DLL after copying out of the archive
So, I already check that the DLL has been rebased before, but I will
still rebase this particular DLL (but not all DLLs currently on the
system). I don't see anyway around this and feel that this is as
efficient as possible.

Thanks for pointing me to the Memento pattern. I will investigate it
and try to come up with a better solution.
