I've got something where I can recompile a .so and the main program 
reloads it automatically (usually) without crashing. To clarify: it 
fails to reload on occasion possibly because it drops a signal but I've 
not seen it crash since I'm careful about when the swap is attempted.

I've not tried building something into the main program to reconstruct 
the source of the library and recompile it. I'd note that I'm being 
paranoid about protecting the interface- lots of magic numbers- and that 
the .so is always generated with a unique name.
