Comment:
In Python one must not use __dealloc__() to free C resources, at least not
unless you are absolutely certain that the Python object does not
participate in circular references.
Does it help to do an explicit `gc.collect()` at the end of `quit_sage`
and only then deallocate Pari? If not we might have to give up clearing
the Pari stack...
