First I think it would be interesting to see how much code is affected
by the problem you describe in your document. Ssince JPython
would have a problem with this kind of code one needs to fix the
standard libraries anyway.
Your example could also be solved by using a GC with a finalization
mechanism that is aware of file objects. It would keep track how many
files are open and eventually do a collection.
All the other solutions seems to make the implementation more
complicated and probably would decrease Pythons already not so good
The main problem with introducing a GC in Python is that a lot of C-code
might directly point to Python objects which could be moved at runtime
by a state of the art GC (generational mark and sweep + copying GC).
