I actually don't think this code can ever have done much, and
since we changed the vnode recycle criteria I doubt it did anything
noticeable and it may not even have been beneficial.

The code used the fact that there a special vnode didn't have state
to reclaim it as soon as it met it, but only if it were the same
hash-chain.

I think the only noticeable impact of this change will be code clarity.

PS: But if you see signs of vnode leakage by all means yell, I could
have overlooked something...
