Reduce memory use of BIND 9.2.x?

[Spam Averse]

Can anyone provide suggestions for how to reduce the amount of memory used
by BIND v9.2.x?

Yes, I know that RAM is cheap, but this box is already maxed-out, and my
memory contraints aren't extreme enough to replace the machine altogether.

I'm wondering if there are particular config options that may increase the
size of BIND's runtime footprint.

Thanks.
