I finally fixed my problem with Gnus. I'm writing this, hoping that it'll maybe help someone out there with the same issue.

The symptom: Gnus checks your IMAP mailboxes forever. The problem I had was with one of my mailbox names: I had a ampersand (&) in there, which had Gnus hanging forever trying to escape it. At least that's what looking at *imap-log* suggested. Activating the logging is as simple as executing (setq imap-log t).

The fix: Change your mailbox's name to something without & and update the .newsrc.eld accordingly. And wait for a proper fix. I'm submitting a bug report now.
