This change is all right, if you fix the chain operations outside the 
locks. Using the off-chain state doesn't work reliably in SMP 
configurations. You also have to ensure that a node in the local chain 
cannot be deleted (unmount). I think you should first write a test case 
which triggers the bug in the original implementation.
