Thanks, that's good to hear.

Bytecode caching (reading the .pyc/.pyo) files is probably silently
failing on an F11 rebuild of the srpm (due to rpmbuild byte-compiling
them all with /usr/bin/python i.e. 2.6 thus giving them the wrong ABI
magic value), but the only effect should be that it runs a little slower
than it should otherwise [1]

Let me know (via the python 3 review) if you run into anything
unexpected, or if there's anything we've missed. [1]

Also: if anyone wants to help package modules for python 3, that would
be most welcome!


[1] I've filed bugs with various rpmbuild macro/script patches to try to
fix this kind of thing; they're all on the Python3F13 tracker bug linked
to from
