I see that Jim later installed a patch increasing it to 96 KiB.

Whatever number is chosen, it's "wrong" for some configuration. And I suppose
the particular configuration that Sergiu Hlihor mentioned could be tweaked so
that it worked better with grep (and with other programs).

I'm inclined to mark this bug report as a wishlist item, in the sense that it'd
be nice if grep and/or the OS could pick buffer sizes more intelligently (though
it's not clear how grep and/or the OS could go about this).
