Clojure bindings for LevelDB
newer byte-streams versions (2+) include a newer version of clj-tuple which avoids the issue which older versions of clj-tuple hae with failing runtime spec validation for a call to defn-.
anyone trying to use clj-leveldb with the latest clojure alphas will get this error when trying to require clj-leveldb:

DBComparator is not interface, so i couldn't use defrecord.
Seems like the latest on clojars is 0.1.1
When I use Clojure 1.6 with 0.1.1, on OS X, it looks like there's a race condition in the iterator. When I do (count (clj-leveldb/iterator <my-db>))
I almost immediately get an error, libc++abi.dylib: pure virtual method called.
When I (count (map (fn [x] (Thread/sleep 1) x) (clj-leveldb/iterator <my-db>))
I don't see this problem.
When I use Clojure 1.5.1 with 0.1.0, on OS X, everything works great.
(def db (clj-leveldb/create-db "/tmp/leveldb" {:key-decoder byte-streams/to-string :val-decoder byte-streams/to-string}))
(clj-leveldb/iterator db)
;=> java.lang.NullPointerException
(clj-leveldb/put db "foo" "bar")
(clj-leveldb/iterator db)
;=> (["foo" "bar"])
(clj-leveldb/iterator db "z")
;=> java.lang.NullPointerException
I would expect clj-leveldb/iterator
to return an empty closeable seq instead of throwing a NullPointerException.
