Startup

Aaron Klotz landed bug 845907. This gives us a consistent way to warm IO caches. This functionality can easily backfire if we end preloading data that does not get used. Uses of readahead should always be accompanied with telemetry to verify it performs as expected. Bug 810454 is the first user of readahead API, it landed with A/B testing telemetry. Omnijar readhead is next, in bug 810151. It results in ~60% drop in omni.ja startup read time on Windows on Aaron’s machine.
