following code produces an error (python-2.6.2). Either of the following

Why is there an error produced in the first place? What is the
interaction
between d1, mod1, and shelve about? This code runs without error in
python-3.1
$ cat test1.py
import test2
newmodule = test2.load()

You don't need all those lines to trigger these exception messages. All
you need in test1.py is the import statement. And in test2.py:
import shelve
cache = shelve.open('persist')
To cure it, just close the cache:
cache.close()
I don't have any idea what the exception means, but this seems like a
logical thing, to close it.
