I'm not entirely familiar with lemock, however...

That isn't how package.preload works. The preload functions are module 
loaders. The loader function is called by require to create the module table. 
The value returned by the loader is then stored in package.loaded.foo and also 
returned by require.

I think all you need is to assign the mock function to foo.dowork_internal.
