Locally, I don't need this change, in fact, it throws an exception saying the
the directory for lib/isolate/runtime already exists.  I haven't tried this
patch on the builder yet, can you think of what might be going on?  Maybe the
previous 'copytree' command is failing all together?

   isolate_runtime_dest = join(LIB, 'isolate', 'runtime', 'isolate.dart')
