We have the function String::Concat in the API now, so I think we can get rid of
the cons_function all together.

       accumulator = Handle<String>::Cast(cons_function->Call(
-          Shell::utility_context()->Global(),
+          Shell::evaluation_context()->Global(),

Since we don't always have an utility context now (unless in interactive shell),
we use the OS object in the evaluation context.

       memcpy(buffer, buffer + length, fullness);
