Damn. No, that isn't quite what I was expecting.
Thanks for the code review.

Blocking is OK for now, but in the long term
something like this might be better:

bool DBUtil::isSchemaLocked(void)
     query.exec('SHOW OPEN TABLES');
         if (query.value(1) == 'schemalock' &&
             query.value(2) == 1)
             return true;
