The manufacturers generally recommend running the water with the aerator
removed for a few minutes after installing a faucet to flush any debris from
the system.

But as someone mentioned, this could be materials from your old pipes as
well. Particularly if you have newer copper connecting directly to the old
iron. Corrosion will happen where the two metels meet and eventually either
clog the pipe at that point or break loose and collect at the next smallest
place - the aerator.

Well, it *was* the aerator. After I thought about it for a minute, it
seem to be the only possible answer. The aerator was clogged with a bit
of some sort of metallic debris. Being that the new faucet got clogged
almost as soon as I turned it on, I removed the aerator and just let the
water run for a while to see what else might show up. Then I went in the
basement and looked at all of the water pipes I could see, and discovered
a galvanized pipe with a pinhole-sized corrosion leak, which might well
have been the source of the problem. Thanks to Speedy Jim for the answer.

Start putting pennies in the piggy-bank; your 50 yr old galv
is due for replacement.
