 Actors representing individual JavaScript threads use the jsd2IDebuggerService Web IDL interface to inspect and manipulate the debuggee they represent. jsd2IDebuggerService is an alternative to the existing jsdIDebuggerService, implemented in terms of the js::dbg2 C++ interfaces.
-The code implementing a thread actor runs on the thread it represents; the server routes debugging protocol packets to actors as needed. All inter-thread communication is handled this way, permitting thread actors and the interfaces they use to be single-threaded, and simplifying their implementation.
+The server interacts with debuggees running in other threads simply by passing entire JSON packets between the client and actor code running on those threads. Thus, all inter-thread communication is handled via the protocol, permitting thread actors and the interfaces they use to be single-threaded and simplifying their implementation. Communication with subprocesses can be handled the same way.
 The jsd2IDebuggerService Web IDL interface presents js::dbg2's facilities to JavaScript.  jsd2IDebuggerService is an alternative to the existing jsdIDebuggerService.
