The new annex.stalldetection is used for transfers from remotes, but not import and export from remotes.

This should be doable, but it will need the transferkeys protocol to be extended to cover the additional actions. --Joey

Note that, the protocol is designed so new requests can be added. The old transferkeys will exit with an error if the new git-annex happens to run it somehow. So it should be fine to add this stuff later on. --Joey
