It is not just memory sessions, any db where transactions have not completed for the first request and / or are not guaranteed to be in a consistent state can exhibit this behavior. This can also cause problems when storing data in a temporary location that may be cleared. This becomes even more troublesome when using multiple transports and you cannot easily use a single session store for all connections/requests, not everything is HTTP :/
