It would give us the possibility of:
- async I/O
- easier I/O prioritizing (block badblocks -w for a while)
- better request reordering (since we now program the sorting
algorithm in it's own thread)
- blocking a swapin when memory is tight (we first have to
free some, so let the process wait a while)
