Hi guys,

Sage with the new Cython has a lot of leaks exposed by valgrind:

==9372== LEAK SUMMARY:
==9372==    definitely lost: 232,533 bytes in 3,757 blocks.

Those leaks are all considered "possibly lost" or "still reachable" with 
Cython 0.9.6.12, so it seems to be mostly an accounting issue 
[valgrind's accounting of possibly lost vs. still reachable vs. 
definitely lost can vary depending on other leaks, but I will spare you 
the details here].

While we have looked into this in the past at various Sage Days it might 
be a good idea to put this on the agenda for Dev Day 1 since this 
currently adds massive noise to the interesting bits when looking for 
memleaks in Sage. I can add a suppression file, but I would consider 
that only a last resort.

Keep up the great work.

Cheers,

Michael
