Hi,

While working on a fix, I got an assertion error during Python finalization because Python tried to import the "io" module whereas the module was just unloaded. Python tried to import the io module to display a warning and display the Python line where the warning was emitted. See the following issue for detail: http://bugs.python.org/issue19421 I propose to block importing new modules (or import again unloaded modules) during Python finalization to avoid such tricky bugs. What do you think?

Though the practice of importing during finalization seems dubious, baning it may be a compatibility problem.

-- Regards, Benjamin
