Is this a recent restriction in MySQL? I think it must be. The MySQL docs have this to say:
https://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html
If you get Commands out of sync; you can't run this command now in your client code, you are calling client functions in the wrong order.
This can happen, for example, if you are using mysql_use_result() and try to execute a new query before you have called mysql_free_result(). It can also happen if you try to execute two queries that return data without calling mysql_use_result() or mysql_store_result() in between.
Which is pretty crazy. But anyways, it sounds like we need to call mysql_free_result
in the MySQL adapter right before execute()
returns.

Looks to be related to the multi_query() calls, I'm working on a patch now to try out calling free result thanks.
I've added a unit test to check for this in MySQLAdapterTest.php
public function test_multiple_multi_query_calls()
{
$this->adapter->multi_query("SELECT VERSION()");
$this->adapter->multi_query("SELECT VERSION()");
}

I've just opened a pull request that fixes this :)
