i'm not a node core dev, but i think this is correct. the require function
doesnt care about the cwd, it resolves alwlays relative to the module on
the filesystem. this is a good thing, because you can always rely on
require, __dirname and local dependency resolution. if require would use
the cwd for resolving module paths, it could not guarantee to always load
the dependencies you've specified for your module.
to set the cwd is more for your application logic, so it can find and store
the resources independently from the install dir.
