Hi Duncan,
> The semantics of sched_yield() changed in the 2.5 kernel.
> In the 2.4 series it meant "sleep a little".
> The new 2.5 semantics are correct (move to the end of the
> run queue) but can mean "sleep a lot" under load.
>
> This already bit ext3 transaction batching, c.f. Andrew Morton's
>
>> [PATCH] remove the sched_yield from the ext3 fsync path
