As said, my approach to debugging this kind of thing is to get out of
python ASAP. And once you manage to reproduce the result when calling
only a couple of python functions, then you use massif or memcheck.
The reason to get out of python is that tools like valgrind can only
give you meaningful informations at the C level, and it is difficult to
make the link between C and python calls, if not impossible in all but
But when you can get this kind of graphs:
Then the problem is "solved", at least in my limited experience.
