Patch Set 1: Do not submit

I'll be replacing this with a new patch set soon.  This code is broken, on Cassandra it crashes and cannot handle the linux-2.6 repository (but its OK with JGit, which is a whole lot smaller).

I fixed the use of Inflater, but its still not counting objects as fast as is necessary to perform a clone of linux-2.6 from a DHT.  Local Cassandra is pretty quick, because the RPC latency is very low.  But going over a WAN (e.g. my desktop to a Cassandra server in another city) is far too slow.  Right now I suspect its because for linux-2.6 we are packing about 2200 commits per 1MB chunk, but we need to walk something like 200,000 commits just to count the commit objects (forget counting trees!).  That is 90 chunks; if the ping round-trip time is 100 ms we need at least 9 seconds just to ping Cassandra for each chunk sequentially.  Since the chunks have no links between them, its actually double that because we need to look for the object in the ObjectIndexTable first.  So its at least 18 seconds to load the commit list.  On local disk this occurs almost instantly.
