I'm not sure I understand this correctly :

let's say that :

1. in old, foobar as uid 100
2. initial dsync
3. user gets relocated, kicked and reconnects to new, then deletes foobar
4. final dsync. dsync somehow manages to understand it should not sync foobar from old to new
5. migration is over, new message foobaz comes in. Oh, I get it, you mean since
uids gets only incremented, this new could not get uid 100 and then confuse the
client index ?
