It seems that in 'slabs.c', slab_rebalance_thread will be created only once. Which variables are required to be protected by lock `slabs_rebalance_lock` ?

There are user commands which can optionally control the slab rebalancer,
so the lock is mostly for that interaction from worker threads. The
restart system also needs to stop the thread gracefully.
