an ordinary invocation of mnesia:create_table/2 already creates a schema
transaction for you; the table either appears everywhere or nowhere.
what ulf was getting at was, if you want the table creation to be atomic
with other normal data operations, this will be very tricky.  however it
is unclear from your example if that was the goal, or if you merely didn't
recognize that create_table uses schema_transactions internally.
