There was a problem hiding this comment.
It's kind of nasty that these throw different errors: the SystemError comes from trying to call readdir on a non-existend directory whereas the Base.IOError comes from trying to do pwd() in a deleted directory.

What is going on with the tests? The failures do not seem related to this change. |

This is a pretty niche issue but it allows `readdir()` to work after the current working direcotory has been deleted, whereas when `join=true` you need a path which no longer exists, so `pwd()` fails and so `readdir(join=true)` also fails.

I don't see how this Win32 failure could be caused by this change, but I don't want to merge this and break Win32. Anyone know if this is a thing that's been happening otherwise? |

rm -rin which case it deletes the file before deleting the directory)
