Right, and whatever changes you make to the OS and its read-ahead configuration
will work for all applications, not just for 'grep'. So, change the OS to do
that. There shouldn't be a need to change 'grep' in particular (or 'cp' in
particular, or 'awk' in particular, etc.).

Quite right. And it would be painful to have to modify all those tools, and to
maintain those modifications. So modify the OS instead. Scheduling read-ahead is
really the OS's job anyway.
