I heard people say they cribbed from the same Chubby paper, but
it's bollocks. It's absolutely nothing like what Chubby implies.
No locks for one thing. To be sure, Zookeeper provides a canned
piece of code which implements locks, kinda like you can implement
compare-and-swap using Dekker's algorithm on a CPU that doesn't
have it. The canned lock creates "sequenced" files (using a ZK
server call that creates unique filenames), then sets some
"watches" (same as CLD offers), then re-reads the directory to
find the lowest number sequential file, which is the winner of
the lock. Haha, only serious. I tested it, it works, but ewwwww.
