Just a note to myself and whoever else cares, should be added to wiki once it has its own page about this:
With single-dbox messages can be copied with hard linking. This means that there can be multiple files that point to the same attachment file. The attachment is now deleted only once the mail file's link count drops to zero, so this works fine.. Why is this specific to sdbox? Does mdbox SIS work differently?
mdbox internally keeps a reference count of how many copies of messages there exists and the attachment isn't deleted until the last reference is gone. So in mdbox even without attachments there exists a bit similar problem: if you manually add/copy mailbox directories the reference counts get messed up.
