For your information: with the demise of Basho, we decided to fork basho/sidejob to be able to keep maintaining and updating it. Head to https://github.com/erlangpack/sidejob for an updated version. Also available on Hex.pm.
If any of the original maintainers on basho/sidejob is reading this: please let me know. I’d very much like to move the basho/sidejob repository in order to prevent confusion on where to head for issues and updates.
