Hi,
I have seen CI failing with some "random" errors which makes submitting a
series of patches a bit annoying, as some patch always fails with some
error, then next run another patch fails.
One of these problems is TestMount.testSymlinkMount. Looks like its getting
EBUSY when doing a rmdir. So probably something still using it?
