Did you run benchmarks?  The initial data is quite alarming:

Starting from a window including this commit gson's test run timeouts
due to taking too long.

Pgoyette's amd64 test run with sources from 2011-02-24 04:20:03 UTC took
1:20h to complete and sources from 2011-02-24 09:20:03 UTC took 1:47h
to complete.

Also, a few test failures seemed to pop up.
