A bunch of minor miscellaneous cleanups

[mebigfatguy]

add hashCode's
move fields to locals to help out the gc
fix Integer comparisons
make sure streams get closed
remove dead code
etc.

Looks good, good catch on some of those (I had another branch where I added hashCode to some of those but haven't committed it yet).

Only one request: Can you remove the "remove dead code" commit? There's a separate issue there (handling correct zone semantics for getAll()) that I'll deal with in a separate commit.

Can you remove the "remove dead code" commit?

sure, but, how do i do that? :)

[afeinberg]

I can do that then, I'll just cherry pick all commits but that.

Good catch...@alex - we should definitely work on that findbugs branch of mine :) Also whenever you cherry pick it can you please also merge it into our 1046 branch?

[afeinberg]

Merged this in.

Roshan and I will take a look to see what the right thing to do is regarding the "dead code" in PerformParallelGetAllRequests is.
