-# SANITY is about "can you correctly predict what the filesystem would
-# do by only looking at the permission bits of the files and
-# directories?"  A typical example of !SANITY is running the test
-# suite as root, where a test may expect "chmod -r file && cat file"
-# to fail because file is supposed to be unreadable after a successful
-# chmod.  In an environment (i.e. combination of what filesystem is
-# being used and who is running the tests) that lacks SANITY, you may
-# be able to delete or create a file when the containing directory
-# doesn't have write permissions, or access a file even if the
