 - access is slow (unless cached, but we can't be sure)

We could solve this (and the other problem) with mlock.

Probably you meant madvise(2)?

For something of a size comparable to the index file held by
index-helper-daemon in-core, I'd expect we wouldn't page too
badly.

No, I meant mlock -- but I guess that's not portable.  madvise with
MADV_WILLNEED will probably do the job.
