That's the worst solution. You are bound to get segfaults if python eventually tries to get rid of the allocated objects itself - and will cause a double free.

If you can't get the problem solved differently, the least thing you should do is to allocate the memory with malloc yourself - then it's fully up to you to release it.

It's called garbage collection, and that's what Python is supposed to do. Why don't you just use the gc.collect()-call Andrew McIntyre & I suggested?
