the API? Most likely; will revise it. Fixes atf-run breaking when running t_psshfs. This does not resolve the underlying issue though, which is atf-run getting confused trying to unmount the temporary mount point by itself (I think). (I'm now wondering if atf should be bothering about unmounting stuff at all. Maybe not. It is a tricky and uncommon thing.)
