SHOW TABLES is a very resource intensive query, specially in multi site setup where there will be many tables in a given database. It's worse when you run through all the tables in the database to see whether the table exists.

Instead I propose SHOW TABLES LIKE which will achive the same thing much more effiently.

maybe_create_table() isn't something WordPress core uses, and should possibly be deprecated along with maybe_add_column(), maybe_drop_column(), and install-helper.php; in favor of dbDelta(). These functions all date to WordPress 1.0 and were more or less replaced by dbDelta() in WordPress 1.5. So we're talking 9 years ago.
