Process context switching is bad since TLB must be invalidated.
I am not a Linux Guru. However if the switching to a kernel-thread invalidate
TLB on mono-processor machine, then I donnot agree with your idea.
On the other hand, I think that it is easy to implement asynchronous read_ahead
as simple asynchronous IO requests.
