If you mess with the require() cache, it's very possible to create a
situation where you cause infinite loops by require() cycles
re-reading the same files repeatedly and synchronously, and these are
difficult to debug.
It's much better to just export a function, and have your consumer
call that function, rather than re-run your module on every load.
module.exports = function(arg) {
// do stuff
}
// the consumer
var blarg = require('blahrg');
var myBlarg = blarg(__filename);
