-- this line made me realize that this file is actually obsolete. So I'm not
sure if it will serve your purposes.

I initially moved part of the implementation of isolates from the VM here (under
lib/runtime), but that got pushed back.

Currently the VM assembles the isolate library using:
dart/runtime/lib/isolate_sources.gypi

One possibility would be to update this file to say:
#source("../runtime/lib/isolate.dart");
