However, the payout queue does say there is 438 BTC waiting to be paid out in 18 blocks. Maybe that's not a lot to you, but it is a huge amount to me.

Just for a little more clarification: if you check the first bunch of addresses in the queue, you'll see those that are a month old or so are usually idle miners and these people are being paid their last payout. These might contain some older shelved shares which is why they look like they've been waiting for ages. Once you start to reach addresses '3 days' into the payout queue; those are usually smaller hashrate miners who've set their payout limit higher than their daily earnings so get a payment every couple of days. After that it looks like around 80% of the queue has only been waiting 20hrs or less.
Eligius also pays directly from mined coins and doesn't ever go into negative balance in order to support itself independent of external capital input, so that 18 block delay is like a buffer to make sure the pool doesn't pay out more than it has or go bankrupt. During times of bad luck the queue can grow longer, but a few lucky rounds usually clears things up quickly.
Hopefully that helps some better understand the payout queue, but that is what I've come to understand through my limited time studying it, I no longer bother as I've never been burned by waiting for payments and I've been here for a few months now. If I've stated anything incorrectly, please someone chime in and let me know.
