Actually, private/local and private/retry refer to the sockets used for

Yep, they're all there. And local is working - at least sometimes (see below) :(

I don't know why a reboot or even just a stop and start of Postfix
doesn't fix this. If you stop and start Postfix, are there any messages
in the mail logs beyond the "postfix/master[pppp]: daemon started ..."
message?

Nothing more than the three warnings I already posted, two of which you see below, and the third being:

2013-06-08T13:10:19-04:00 myhost postfix/master[4076]: warning: 
master_wakeup_timer_event: service tlsmgr(private/tlsmgr): Resource temporarily 
unavailable

But, I have more details after some testing...

First, mailman is definitely working. I tested sending to one of my test lists with just two people on it, and it works fine:

I tested with another list that has 6 people on it, two of whom have their vacation message enabled (I use postfixadmin vacation), and while all 6 recipients got the message, there were two messages that got stuck in the queue that are related to the vacation message:

As you can see, only the two vacation messages are deferred with transport unavailable.

It also appears that the problem manifests with NESTED lists:

I imagine that the two problems are being caused by the same problem, whatever it is...

It also seems to be something to do with how many recipients are involved. One or two appear to be ok, but more than that and it gets iffy...

Appreciate any more thoughts on this weirdness, because I'm stumped....
