So I have a pair of questions:
* how far have wiresong's FileSystem and Pharo's FileSystem diverged?
(And how do we bring the two back together again, if necessary?)
I doubt there's much divergence. I synced with the Pharo folks as they were putting it in to their base image, and that was a pretty mature implementation, so I'd be surprised if there was anything difficult to deal with.
* How do we fix the problem?
Well, I'd be happy to see Filesystem in Squeak. :-)
I know Chris is worried about breaking Magma, so we'll need to be careful, but we can do that.
