Why is this not a PassRefPtr<NewScriptState>?

[haraken, 2014/04/12 02:12:28]

Because we're not intending to pass an ownership of NewScriptState here. A
general programming rule of NewScriptState is to use NewScriptState* on stack
and store RefPtr<NewScriptState> in an object that wants to keep the
NewScriptState alive while the object is alive.

     {
         return create(adoptPtr(worker));
     }
