The source and target mailboxes are on the same user account, same
partition, but strace shows that link is not used in 2.3.8. The
following traces are obtained with strace, when copying messages from
testbox to testbox3 with cyrus 2.2.12 and to testbox4 with cyrus
2.3.8. In both case, I used the same configuration/mailstore/client:
- cyrus 2.2.12:

There must be something really wrong in my configuration...
