Exponential Lease Time

Definitely deserves further testing. We've done some scripting before
and it didn't contribute to a noticeable load.

After the lease expires, it appears that the "renewal" variable gets
wiped. Again, this could use some more testing.

I pretty much hacked this up. I'd love some feedback from folks who
are more familiar with how the variables work and are designed to be
used.
