How do I simulate an ELOOP? about fakefs

Sounds like a bug in fakefs, PR welcome if you can figure out how to do it properly 👍

In general Dir.mktmpdir can be useful to cover these edge-cases.

This one's been hard to track down, I probably need to use a GUI debugger. Anyway, I can tell you that within the FakeFS::FileSystem#normalize_path method, the base and part inside the reduce block are always "/" and ".", respectively.

Indeed, that's what I was doing already.

In the end I couldn't solve this without breaking other things. I had to put a break in Pathname#plus, plus a couple other minor tweaks, but I couldn't do it in a general way. Maybe someone smarter than me can fix this someday. For now I just temporarily deactivate fakefs in the specs.
