Please note, that I was using the 'Reload modules' functionality of
the software system in use, rather than the reload() function
directly. I admit, though, that in the background it just may call
reload() ...

With all the problems of the reload() function, I still hope, that
there should be possible to write a safe module 'reloader', that would
fix the references, as required (e.g. by changing the
variable.__class__ references). This should be provided by every
serious Python development environment.
