By incentive, I meant incentive for me, not for you :) I think this
could be really helpful for other problems if this kind as well.

Using massif with code using a large number of python code is clearly
a no no, since it uses so much malloc. Sometimes, you can just stop
the thing when it is growing up, and watching the resulting graphs.
But this is no fun, and if you have no time...
