We're always busy, too, so I can understand... in fact I've been too busy to follow up :). I just noticed that the pull request are still sitting there, though. If you can take a look that'd be great, and we'll try to get some more patches up on jira or github.
We'd like to contribute more back, but want to make sure we have the process down right, as some of the other changes are more substantial (e.g. adding groundwork for azkaban metrics). If the official Azkaban repo is falling dormant, we could push to our own repo, but I don't think that's health for the community.
