Cute. One thing I'm not quite sure I understand is how anything gets written back to your state database if you're not in leaky mode, though. (I probably need to read the patch in context, but it's 8 in the morning, and I'm about to go to work, so I'm probably missing something obvious). Does it all magically get updated from the tree when the connection gets closed or some such?

The relevant code is:

if (rc == FAIL || !leaky)
dbfn_write(dbm, key, dbd, sizeof(dbdata_ratelimit));

i.e. if the rate is low, or if we are strict, update the persistent state.
