Description

Should add a new (binary?) histogram to indicate whether we decided to prefetch or not. I think 50% rand() is fine for this, unless there are other startup experiments we want to do at the same time.
I guess we want to avoid this spilling on some channels. Which channels would it be suitable for? aurora + nightly? only nightly?

Aurora/nightly sounds good to me.

Maybe we should try no prefetch + no preload?

Worth a try, but that requires being able to randomly remove prefetch files. Seems like something best done in own bug.

Specifically I'd like to see if no prefetch + no preload is faster than no prefetch + preload.  So both have no prefetch.

Patch v1.

r+ if you change STARTUP_USING_PRELOAD to STARTUP_USING_PRELOAD_TRIAL or something. It's ok to reuse a histogram for a slightly different meaning, not ok to change histogram bucket distribution, it really confuses our frontend.
