Patches for any of these problems would be welcome.
As freadahead seems to be most pressing, it sounds
like that's the best one to work on first.

That sounds like a challenge! How about using
the following patch? Does it work for you, if
you define SLOW_BUT_NO_HACKS? If so, perhaps
we should just make SLOW_BUT_NO_HACKS the default.
