Why would it bother? XFS tends to be a filesystem that you'd only use
for core files in environments where you have a system manager that
knows what he is doing. So there, maybe "try forever" is the right
thing to do.

Things are a bit different with some random unreliable USB stick FAT32
filesystem that just died on you, with a normal user that just removes
the thing or doesn't even notice that the stick is now dead. There the
"try forever" is totally the wrong thing to do.
