+will only return a non-zero exit code if it finds a fatal
+error.  An example of a on fatal error is an incorrect data block
+reference count causing a block to be considered allocated when it in
+fact isn't.  Ignoring errors for a long time is not advised, you
+really should be using thin_repair to fix them.
