230	Mutexes taken when spinlocks held	Jakub Jermář		"In the current revision, changeset:mainline,402, the stats code attempts to lock the address space mutexes while holding task locks:

{{{
get_stats_tasks()
   spinlock_lock(&tasks_lock)
   task_serialize_walker()
      spinlock__lock(&task->lock)
      produce_stats_task()
         get_task_virtmem()
            mutex_lock(&as->lock)
            mutex_lock(&as->area->lock)
}}}
