Note that this solution will break due to the string passed to require
being used in package.loaded.
e.g. if you have the 5 files:

myprogram/main.lua containing: `require "a.foo"; require "b.qux"`
myprogram/a/base.lua
myprogram/a/foo.lua contaning: `require "base"`
myprogram/b/base.lua
myprogram/b/qux.lua containg: `require "base"`

Then b/qux.lua will *not* get what it expects
