  In task_kill(), remove the task from the tasks_btree before proceeding.
  Thus, when the kernel finds the task in the tasks_btree and locks it before
  releasing tasks_lock, it is guaranteed that the task will not be destroyed
  until the lock is held. If the kernel needs to unlock the task, do some operation
  and lock it again, it should increase its refcount before doing so. In that case,
  when releasing the lock, it must decrement the refcount and if it reaches
  zero, it must call task_destroy().
