Working on it, but Guile's initialization is a little complicated in places. In the (much) longer term, I think finding some solution for Emacs other than unexec would be better, if we want to permit extensions in general, because unexec-ability seems like a pretty onerous demand to make of all libraries one might want to use. (Luckily, I suspect most such libraries don't need to have *any* code run before the unexec step, so loading fresh versions in the new process isn't a problem; that just doesn't work in my case.) But that's a whole other matter...

I was kind of hoping CANNOT_DUMP might give me a shortcut to something I could actually run. :-( Actually, it kind of does, if I avoid bootstrapping; I just have to figure out if each bug is in my work or in the Emacs code base I'm starting with....
