The only thing I'm concerned about here is that moving the mutex may result in more contention within mariadb as it can be required to hand out more results concurrently. Testing shows about a 20% improvement in dealing with tests/q7688979.1.4k.chunks.sql, but this may not be a great test case. At least moving some of the member variables to local makes it easier to relocate the mutex.
