I expected as much. But just to make sure we're on the same page, after 
converting a user, only dovecot.index and dovecot.index.log exist in a 
user's index directory, no dovecot.index.cache. However, all of the 
user's folders do have indexes, not just the inbox. That is the expected 
result, correct?

I have the source mail spools on NFS as well.

Fair enough, I'll have a look at this if it does make a significant 
difference, although I'm trying to keep source changes minimal :)

Understood... that's going to be nasty though, it's just a matter of 
degree :)
