Code review comment for lp:~mwhudson/launchpad/less-import-requestMirrors-bug-487357

Hi,

This branch extends the contract between the code import 'worker' and 'monitor' scripts by specifying that an exit code of 2 means that the import was successful but didn't import any new revisions so there's no need to request a mirror of the import branch. I expect this to substantially reduce the load on the puller, as currently about half of all branches pulled are import branches with no new revisions.

I've had some pre-imp discussion with Tim, Jono and Aaron about this.

Cheers,
mwh
