@ko1 Thanks! I've wanted Ractor.shareable_proc since the very first time I tried using Ractor. 🙂 Net::IMAP::Config still isn't completely ractor-safe, because Config.global needs to be stored/updated in a ractor-safe way. But I'd like to handle that before the next major release.

@nevans
FYI: I found that our production relies on net/imap and because of the lack of this patch, our production failed on our CI on Ruby edge. I would really appreciate it if you could release a new version soon with this patch.

Thanks.

@ko1 My apologies. I was postponing the release until I had time to complete the QRESYNC PRs, but I don't need to do that (and it's about time to branch for the next release series anyway). I'll push a new release today.
