I look in the Mailman logs dir. Nothing really onerous that I see. I look in smtp and see what looks like normal processing. e.g. one of my lists looks like it had a number of messages just a few minutes ago, but I have not seen them yet where normally I would expect to see them almost instantly.

Those messages have been delivered to the MTA. If the list has just 3 eligible recipients, that looks backlogged but otherwise normal. If the messages haven't been delibvered, check the MTA (mailq or whatever).
smtp-failure seems to contain not much else other than reports of bogus email addresses. I've used this as an opportunity to weed out most of them, but there are still messages that had been queued up for them so I'm not sure how long it will take those to fail delivery. For example if I "tail -10000" (ten thousand) that file and grep out the 5 main bogus email addresses, I get one single line :
Jan 04 12:07:50 2010 (50034) Low level smtp error: (4, 'Interrupted system call'), msgid: b100e8e71001021626l470dc99fmcea7aceba072823b@mail.gmail.com
But i have been unable to find out what this means. But given that I only see it once I am not too worried about it really.
Can someone tell me where to look as to why stuff is getting backed up in the outgoing queue?
Your MTA is checking too much during SMTP from Mailman. It shouldn't be doing address verification or even domain verification on remote recipients.
What is in Mailman's out/ and retry/ queues at this point? The out/ queue is almost certainly backlogged.
You could try moving all the out/ and retry/ queue entries aside and then removing the bad addresses from them with the script at http://www.msapiro.net/scripts/remove_recips and then replacing the entries a few at a time.
If the system is still slow, search the faq at http://wiki.list.org/x/AgA3 for "performance".
