Asynchronous is overloaded in modern software practice.

Do you mean (a) stop the script execution from another thread, or (b) 
have the native method suspend the script such that the current thread 
sees a return from whatever JS_EvaluateScript API (e.g.) call it made, 
but can resume execution later where the script left off?

Again, (a) is a matter of causing some native, or some hook such as the 
branch callback, to return false.  With multiple threads, you can use 
conditions and locks to signal and probe appropriately.  NSPR provides 
portable veneer.
