The base Python 3.1 is installed there, but without any modules.
Below is the list of Python 2.6 modules installed. Search that
page for "py3", and you get nothing.

On a hosting service, a raw Python with none of those modules isn't
very useful.

This is what I mean about Python 3 not being ready for prime time.

We install modules as clients ask for them. No one has yet requested a
Python 3 module.

Well, it isn't useless.

Are you sure? I wonder if there might be some race condition that could
make it fail.

I didn't even know about (or forgot) this change. Yucch.

Luckily, no: (lib. docs on exc_info())

This function returns a tuple of three values that give information
about the exception that is currently being handled. The information
returned is specific both to the current thread and to the current stack
