I apologize if I'm doing something silly here, but for some reason I can't
seem to replace/delete a key with a new value without increasing the size
of the database. I was experimenting with the gist below where i simply
write a value, delete the old value, and write it again. The 2nd write will
never go through...any ideas what is wrong with this scenario:
