If you can write a unit test now that would fail using Jython, then 
you're going to be reminded quickly.

And perhaps there will be changes to Python
- that make the oppen().readlines () version work in fully garbage 
collected environments; like closing the inner file handle when the end 
of the file is reached
- that suggest a different solution; like declarations on local 
variables that say "call destructor when object goes out of scope"

Then, having more complicated code today doesn't buy you anything.
