[PATCH] AS: don't anticipate against a task's initial I/O

From: Nick Piggin <piggin@cyberone.com.au>

In the anticipatory scheduler, don't anticipate against the very first IO
request which a process issues.

This solves a very specific problem wherein a process starts, submits a
single IO then exits.
