This was a couple months ago but I forgot to mention it here!
Here is the commit:

The problem was that, on Windows, loading a native module with a file system path that was longer than 256 characters hit the classic MAX_PATH windows issue. Node actually has a way to successfully load files with long paths, and that way was applied to all path handling except in this one particular spot. It just so happened that I was the only person in the world trying to load native modules from a long path on windows it seems!
