Ok, I understand better. When you send thread queries to an offline mysql server and you change map, server is blocked the time all queries are processed and it takes like ~1 second (tested in local only) to figure out there is no connection. So 20 queries and server is locked for ~20 seconds. For sure it should not block the server while doing the job and could be lead to crash depending the context and plugin running. Will see if something can be improved.
