> Memory-mapped I/O on Windows causes issues with hard-links; we're unable to
> delete hard-links to open files with memory-mapped segments even using nio.
> We'll need to push for close to performance parity between mmap'ed I/O and
> buffered going forward as the buffered / compressed path offers other
> benefits.
