Fix broken require() behaviour

I recently reported a problem with require() being broken: it caches 
failed require()'s as having been successful.  See the thread starting here:

Rick Delaney kindly posted a patch to fix this:

but it doesn't seem to have been applied anywhere yet.  Is it going to be?
