AFAIK (i.e. as far as my understanding of GRUB dessign goes), there's no
filesystem write involved in that.  There are userspace filesystem _reads_
and userspace raw _writes_, but that's all.

For what GRUB is concerned, I don't think there's any kernel filesystem
access involved either, but if such happens for other reasons it might fuck
the userspace filesystem reads done by GRUB, which is probably the source
of the problem.

This is going beyond me now.  I'm tagging the bug as "help".  Probably worthy
for an XFS guru, but not for me :(
