Please, note the order of the calls to mnesia:start/0 and
mnesia:create_schema/1 in Martin's reply.

In Ben's original posting the calls was in reverse order.  As an
effect of this, Mnesia was started in a disk less mode. Later when the
mnesia:create_schema/1 was invoked, in order to initiate the database
on disk, it failed since Mnesia already was started.

	Starting Mnesia in disk less mode is rather convenient, when
	you want to try some API functions out in the Erlang shell,
	without polluting your disk with temporary toy databases.
