Imagine a situation below;
JS:
var myObj = { a:1 };
NATIVE_METHOD_1(myObj);
..
..
NATIVE_METHOD_2(myObj);
..
C++
FS_OBJECT.NATIVE_METHOD_1 { save a pointer to 'this(fs_object)' into argument 0
}
NATIVE_METHOD_2 { read the reference .. ahha (it has fs_object) .. }
..
Hope it's clear. This is how node.js / jxcore works. Right now it's not a big
deal since I've implemented some tricks around the issue but this is a very
common use and affects performance etc...
