[Cython] cython doesn't compile cdef'd variables of type set?

I haven't heard anything about Cython itself running under Py3. Stefan 
made runtests.py run under Py3, and then you need to first run it under 
Python2 with --no-cleanup, and then under Py3 with --no-cython (so that 
the C files generated using Py2 is compiled under Py3).

So this is where your scheme breaks down currently.

Perhaps this was fixed without me noticing it (if so I've broken it 
again in cython-devel I'm afraid, but that should be easy to fix).

If you want to fix this, then the matter disappears. OTOH I think 
supporting both Python 2 and Python 3 for running Cython could bog us 
down somewhat, at least it is not Guido's recommended porting strategy 
(which is staying with 2.x until you can make a total switch). Users 
will need to keep 2.x around on their systems for years to come anyway 
so I don't think it is something we should worry about at this stage if 
it means much work.
