    kernel: Add a final p_lock wait loop before kfree'ing the process
    
    Since p_lock can be acquired during the process removal, there
    needs to be a final wait loop after the proc has been removed
    from all queues, just before the kfree(p).  It will be a very
    rare case but it definitely can still occur if e.g. the SYSCTL_OUT
    code blocks on a VM fault or something like that.
