I would never be so ambitious. But as you can see, it's only 4 lines of 
changes. The desired functionality is already present in BDB, there's 
just no convenient user-level access to it. My patch provides that API 
access. I've also submitted the patch to Sleepycat (bug#10619) so 
hopefully it or something similar will be available in the near future.

The implementation is not the slickest in the world, but it works as 
intended.
