We're spending a lot of time reading image hashes up front.

TestInfo.__init__ does:
            self.image_hash = open(expected_hash_file, "r").read()

(which probably leaks a file handle).

run-webkit-tests reads image hashes when it gets to them.  We could to (and
probably should).  There shouldn't be a thread-safety issue because only one
thread is ever processing any given test.
