Ok, I've found the reason for this. Setting

cures the problem. Nevertheless I think the original problem is worth debugging. I'll provide the necessary debugging information, if someone is interested and tells me what to do.
While it's worth debugging, there's usually little reason to not use hardlinks, and the performance gain with large messages is astounding. For those who aren't familiar with hardlinks, when messages are moved from one folder to another via an IMAP command, I believe they are copied/deleted instead of moved. If hardlinks aren't used, the message must be replicated, then the original deleted, which on a large server with large messages, could significantly increase I/O. With hardlinks, a link is created, and the original link removed. Very little I/O.
