Indeed. It seems Cython 'memoizes' counters for a module context, then
if you compile twice, the counters are not reinitialized. Or somethig
like that....

You know, module or class level globals could be rally evil :-) ...

$ cd Cython/Compiler/
$ find . -type f -print0 | xargs -0 -e grep -nH -e
TemplateTransform.temp_name_counter
./ParseTreeTransforms.py:549:        TemplateTransform.temp_name_counter += 1
./ParseTreeTransforms.py:550:        handle = "__tmpvar_%d" %
TemplateTransform.temp_name_counter
./TreeFragment.py:122:            TemplateTransform.temp_name_counter += 1
./TreeFragment.py:123:            handle = "__tmpvar_%d" %
TemplateTransform.temp_name_counter

Is the .temp_name_counter counter ever decremented? Could be this the
root of the problem?
