I know that you're allergic to the word "mode", and to a certain
extent I both understand and agree. However, you are fighting a
strawman, because I didn't use that word. There is nothing modal
about what I propose.
You're right that we can't keep objects around forever, because it
will cause swapping in situations where it otherwise wouldn't occur -
but don't throw out the baby with the bath water. The rest of my
proposal is still valid: vcl_hit() still needs to be able to make a
decision about using the existing object or replacing it, vcl_miss()
still needs to be split in two, etc.
