Suggestion: Issue Maintenance on Github

[chriscz]

Hi there,

I've noticed several issues are very old or seem to not be relevant anymore, it would be great if these can be closed because they create the impression that DelayedJob is buggy or unmaintained when this is clearly not the case.

The reason I bring this up is because I've been looking at the background job landscape of ruby recently for database-backed job runners and it looks like delayed_job is the only maintained one that works with MySQL.
