Mnesia itself does not impose any hard limitations in this regard. But Mnesia
uses ets and dets as table storage and they have (configurable) upper limits.
dets does not impose a limit itself, but each dets table consumes an open port.
In practise there are other considerations that limits the number of tables,
such as memory consumption and performance.

See http://www.erlang.org/doc/efficiency_guide/advanced.html for more details
about system limits.
