Static nodejs variables in embedding #1367

• Node.js Version: v8.x
• OS: MS Windows 7
• Scope (install, code, runtime, meta, other?): embedding

I use nodejs to run javascript code in my application. I run code and files. But after running code, run from file works incorrect. I think problem is in static variable eval_string that is not be freed after previous run and on next run it have unpredicted value. And on next run bootstrap script checks if process._eval != null and tries to run "code". I didn't find any place, where eval_string would be set to nullptr. And I think, other static variables also can interrupt running scripts.
My question is following: Is there way to set nodejs variables to default without changing node sources?
