looks fine on linux, did some end-to-end tests without issues but I don't think we tested macOS and windows (which could have different behaviors)?
i think we can merge as long we cover testing on windows somehow:
- address the duplicate key thing in ipfs/go-ds-flatfs#142 (review)
- test
ipfs addwith this PR on Windows- see concern in ipfs/go-ds-flatfs#142 (review)
- test
ipfs addwith this PR on - switch this branch to new release of flatfs before merging
