[mythtv] wierd backend memory usage/reporting?

So I updated recently (to r11068, not quite 0.20) and tonight I noticed
mythbackend appeared to be using a TON of memory:
mythtv at cerebro:~/myth_dev$ ps aux | grep mythbackend
mythtv 19034 0.3 5.6 1105592 58464 ? Ssl Sep06 29:32
/usr/local/bin/mythbackend --daemon --logfile /var/log/mythtv/mythbackend.log
That's right, 1.1 GB.
I only have 1 GB of ram, and only 512 MB of swap, so I was a little surprised
mythtv at cerebro:~/myth_dev$ free
total used free shared buffers cached
Mem: 1035072 1020308 14764 0 620 626464
-/+ buffers/cache: 393224 641848
Swap: 498004 248692 249312
Unless I'm mistaken, free says I have 641 MB free, not counting the cache. My
total virtual space should be 1 GB (ram) + 0.5 GB (swap) = 1.5 GB available,
but I have 1.1 GB (backend) + 0.6 GB (free) = 1.6 GB, and that doesn't even
include 400 MB of mysql (or other processes).
Can someone please explain this to me, because either my machine is converting
energy into ram or I don't really understand what ps or free is reporting :)
