Since the aim was to create virtual disks, indeed, I only used the
loop device in Linux. But since you encountered the very same kind
of behavior, I made the assumption that the problem was at a more
"general" level in Linux, the way fs is handled via some cache strategy.
So, yes, for me : only on loop device [others untested].
