Comment(by ncohen):
> Maybe I'm wrong (probably) but the exponential growth suggests to me
that, during the copy, some sort of nesting is going on. If the problem
were merely a failure to deallocate, the growth should be merely linear,
shouldn't it?
Yep, right `O_o`
> Python has a garbage collector -- is there any way to peek inside the
structure of `P`, and see what constitutes it?
I've got no idea how to do that. And if that were the case, it would have
to deal with Cython too !
