It fixes a bug where a recently unpacked tail might race to the disk
with bytes modified via DIRECT IO. The common way to trigger the bug is
via a mixture of direct io and regular file access at the same time.
Most people won't see the bug, since it is uncommon to mix regular and
direct io that way.
