I've seen similar stuff that I can't quite explain on a fairly large
number of sites.  Every now and then cron.php will get into the
cache_page table as a 404.  The only solution I have is to "delete
from cache_page where cid like '%cron.php';"

One note - the cache is only used for anonymous users which explains
why the authenticated users in step 2 of your scenario see the actual
page.

If you have a way to get the step 1 (i.e. the 404 for anonymous that
should actually be a page) I'd love to hear it.  There's certainly a
bug in here that we should solve.
