Retry calls that raise file system errors during cleanup
If a test case mounts user-space (puffs/fuse) file systems or spawns
server processes that create pid files, the termination of the
corresponding processes does not guarantee that the file system is
left in a consistent state immediately. The cleanup routines of both
components (file systems and daemons) may still be running.
This situation causes a race condition between the termination of the
auxiliary processes and our own file system cleanup: the file system
calls performed from within the cleanup routine may raise errors
because the file system is still changing underneath. (E.g. we first
enumerate the contents of a directory and get file X, but when we
attempt to delete file X, it may be gone.)
Deal with this by retrying failing file system calls a few times and
ignoring "expected" errors before giving up.
