Response from Marcel by private mail:

I see the problem, and I'm not very sure how to solve it.

I think the sidecar should be moved along with each single file, ideally
atomically, so when an operation is cancelled, a clean situation remains.

If a file transfer fails, then usually the subsequent transfer of the sidecar
will fail as well. But I see we want to be sure.

I had the idea to implement it in the ioslave, but I'm not sure the copy()
method is always called. We'd need to double check that. If get() is called,
no other file operation can be managed.
For each file we'd need to check if a sidecar is available, and this can take
a long time when many files are moved. This means the task needs to be done
asynchronously. The ioslave would come really handy.
