python: Remove 'del g' from the docs, replace with 'g.close ()'.
'del g' is a trap for the unwary. If the handle has any other
references, it does nothing (in fact, it can be actively dangerous if
the user was expecting the appliance to go away). In non-CPython it
can be delayed arbitrarily long.
Using 'g.close()' on the other hand is always safe.
