Pull request has comments in need of work; I don't have time. What to do?

[swaldman]

So my pull request re posting notifications of new Dreamwidth entries to Twitter got reviewed, and has comments that need to be addressed. However, I don't have time or headspace to devote to DW dev work at the moment, so if this is going to make it in before it bitrots completely, it would probably be best if somebody else took it on. This leads to two questions,

1. Anybody want to take this on? I think it's mostly there, but needs tweaking as per comments. And probably some fairly thorough re-testing, since things may have changed with Twitter and Net::Twitter since I wrote it 18 months ago.
2. More generally, what should I do in this scenario? Is there some way in which I can unassign myself from the PR? (I'm not sure that there even is an Issue to unassign myself from; I did this work while we were in bugzilla)

Thanks.
