Yes. The desirable behaviour for laptops is to defer writes
for a very long time, or until the user says "sync".
Mechanisms need to be put in place so that if there are pending
writes and the disk happens to be spun up for a read, we take
advantage of that spinup to push out the pending writes at
the same time.
This behaviour should be all be enabled by a special "laptop mode"
switch.
There's nothing particularly hard in all this... I'll do a 2.5
version at some stage.
