Creating a new object immediately after deleting one with the same key

Distributed deletion, and garbage collection is a really hard problem.
Riak has a couple different ways to do it talked about here:

The default mechanism tombstones the key, and then waits 3 seconds
after the write has reached stable state (on all the primary vnodes of
the preflist), and then blows it away. Although, this is configurable,
it's probably not what you want to change. You should pass the
deletedvclock=true, when doing the get, and then pass back the vclock
on write. There is more information in the linked doc.
