Sure, I am tempted to drop in 0.11-devel and see if it compiles the Sage 
library and if it then even starts Sage :). Hopefully 0.11 will come 
soon and we will find a way to integrate the refcount nanny as a special 
mode during doctesting of Sage, i.e. during compile time of Cython 
activate it and if we then somehow could have the doctesting framework 
have some mode where *every* reference was watched this would truly 
rock. If this is expensive performance wise it doesn't matter since it 
would be a special debug mode :)
