Trying with pypy ("just to see"), I got even more reproductible segfaults - 
even with valgrind.

Turns out, I was not keeping strong references to ctypes buffers, which get 
very quickly collected with pypy and memory reused for something else, leading 
to a quick crash.

Now, I don't get yet why cpython was not crashing more often, even if I forced 
gc.collect() . Less memory recycling maybe ?
