updatedb memory eating bug

It seems that when running updatedb (as root, of course), major amounts of
memory are consumed, and not freed once the database update is complete.
My system has 256mb of RAM - about 205mb free on initial X login. As I run
updatedb, I watch the memory slowly get eaten to about 110mb free. When
updatedb is completed, it does not free all of that memory.
Steps to Reproduce:
1. Login as root
2. Update the slocate database by issuing the command 'updatedb'
3. Watch memory
Actual Results: Memory is eaten
Expected Results: Memory should be freed once the application has
completed the update.

It's being used by the kernel for cache. If you'll note the memory
statistics, the increase will pretty much all be in the 'buffers'
or 'cached' category.
Once it is finished then, is there a way to free up the buffers & cached
sections of memory since this wouldn't be in use?
No; the kernel will clear out the cache if it needs it for other
