That's what's up for debate. When Python 3.4 comes along, it will be
backward compatible with Python 3.3. But if we keep modules in
/opt/csw/lib/python3.3, Python 3.4 will not see them, unless we do
something. We would either need to patch Python 3.4 to look into the
3.3 library directory (Is that good? I think not, it seems ugly. Prove
me wrong if you wish!), or we will have to rebuild all Python 3
modules to support 3.3 and 3.4. Why not have a shared Python 3 space
