Ship it!


Currently there's only one user of ItemFetchJob (and thus this code) in threads I'm \
aware of, the legacy KRes compat bridges. Since it's supported and working, I think \
we need the mutex to keep it that way, even if not used much right now.

I've looked at KMime AddrSpec/Mailbox, which probably should be changed to storing \
the joint version rather than three parts, but that can't be easily done in a BC way, \
the members are not in a private class.
