> The filesystem tests in {{test_fs.py}} that are parametrized with all the tested filesystems have some "state" shared between them, at least in the case of S3. 
> When first a test is run with our own S3FileSystem, which eg creates a directory, this directory is still present when we test the s3fs wrapped filesystem, which causes some tests to pass that would otherwise fail if run in isolation.
