Profile pauses should be less than 500 ms even when handling 120,000 samples (2 minutes @ 1000 hz). Code objects are referenced by hex address: "code/cafebabe". Test for retrieving code objects over the service. Remove old profile tool scripts. Replaced by dprof (https://github.com/dart-lang/dprof) and Observatory UI for profiler. Support for stable service refs to implicit closures and dispatcher functions.
