The problem is that since MyISAM's concurrent_insert is on by default some concurrent SELECT statements might not see changes made by INSERT statements in other connections, even if the INSERT statement has returned. The solution is to disable concurrent_insert so that INSERT statements returns after the data is actually visible to other statements.
