Sure, but creating a new ScriptContext has a substantial overhead.
AFAICT sharing the engine only enables caching the compiled scripts, as 
well as making Compilables work. IIRC both (reuse context, reuse engine) 
had a similar impact on performance.

I'm not sure what you mean. AFAIK Nashorn caches scripts automatically 
as soon as you start reusing your engine, you don't even have to use 
Compilables.
