New issue 331 by [email protected]: assoc_maintenance_thread unlocks mutex without locking first
http://code.google.com/p/memcached/issues/detail?id=331

Checked in memcached-1.4.15.

assoc_maintenance_thread() (assoc.c) has a piece of code with:

slabs_rebalancer_resume();
....
slabs_rebalancer_pause();

The problem is that slabs_rebalancer_resume() is a mutex unlock() operation - and that is not allowed (the pthread declares its behavior as "undefined") before the mutex is ever locked...

I guess we need to call slabs_rebalancer_pause() in the beginning of assoc_maintenance_thread()?
