> "When doing a get on a node that doesn't exist, intermediate nodes are created.  E.g., cache2.get("/one/two/three", "key1") actually ends up creating /one/two/three first, and after the JBCACHE-875 fix, /, /one and /one/two will be WL'd for a get() on a nonexistent node!!  Shouldn't the loop just be short-circuited such that at any point, if the next node does not exist and the lock_type requested is READ, just return a null?  Saves us a whole bunch of unnecessary WL's ..."
> Don't bother creating such intermediate nodes.  If the intermediate nodes don't exist, how could the final one exist?  :S
