I'm presenting the argument for threading. Per is presenting the work
around using asynchronous queries via mysqlnd. I did read that link a
few days ago, "Although the user can send multiple queries at once,
multiple queries cannot be sent over a busy connection. If a query is
sent while the connection is busy, it waits until the last query is
finished and discards all its results." Which sounds like threads ->
multiple connections to not run into that problem.
