Yes handling AO errors like this was the intended way
I thought I had tested it at some point and intentionally changed the
signal checking for this case (because normally SIGBUS cannot be
blocked). Anyways if it doesn't work it's definitely a bug.
If you fix it please make sure to add the test case to mce-test.
