OK. Yeah. The Molex "K.K." series has that type of pins.
I happen to have some of those (or some that are extremely similar) on my desk, right now. Some guy on ebay was selling a "sample" set, with two M headers and two F shells for each size, that included 2, 3, 4, 5, 6, 7, 8, 9, 10, and 12 pins (although I also received two 14-pin F shells, as freebies), along with enough pins to fill all of the female connector shells. And I couldn't resist, since it seemed a lot quicker and easier than trying to order them all separately as free samples from Molex's site, and was pretty inexpensive ($10.50). They just got here, not more than ten minutes ago.
They ∗DO∗ look good. Looking at the latest and greatest Mouser(.com) catalog (#619), I don't see an exact match for them, in the Molex K.K. series. But they're pretty/very similar, and use almost-exactly the same types of crimp pins, in the female shells. (I guess I'll email the seller, to see if he knows the exact make and model, etc., in case I want to get more of them.)
These say "2510", on all of the F shells. They have M headers that have a basically-flat friction-lock type of "riser", on one side (i.e. parallel to the pins' common axial plane), which also includes detent-type locking "bumps". And the F shells have small "guide rails" that protrude out, most of the way up each edge of the side that contacts the headers' risers, to keep them aligned as they're plugged or unplugged, and to prevent any lateral movement. They feel pretty SNUG, when connected, even WITHOUT any of the pins installed. And the pins have basically the same-shape single-wipe contacts as the Molex K.K. series. They are basically flat springs, which come down from the wire/crimp end of the pin, bend about 135 degrees at the bottom, and go about 4 mm before bending back toward the rest of the pin at something less than 180 degrees, and continuing back to the vertical part of the pin, where they actually have a tab that goes THROUGH a small slot in the pin and then is bent, to retain it in the slot.
No time for more, right now. But thanks for all of your other comments, too!

My preference for high reliability is contacts that have a "wiping" action,
which can be seen in the "Centronics" style connectors used on the back of a
printer, which I've also seen in sizes of 24 and 50 pins and there are
probably others. Some "external" connections on SCSI cards seem to offer a
miniature version of this, like on my Adaptec 2940uw, and the SCSI-wide
connector is similar in a 68-pin version as well. Some of the pin connectors
I've seen/used over the years are based on a similar idea, though I don't
have part numbers handy. The one half is a square pin (though sometimes
round ones are used too), and the other half is a bit of sheet metal that's
"folded" several times (think of an "@" character :-) and has some continuous
spring pressure holding it up against the other half. This is in sharp
contrast to a bit of sheet metal that's supposed to wrap itself around a pin.
