I saw it happen before my eyes now.  It happens when gnus fetches new
news, I think.

This is what was in the *Messages* buffer:

Checking new news...
Reading active file from cloud via nnimap...
Opening nnimap server on cloud...done
Reading active file from cloud via nnimap...done
Reading active file via nndiary...done
nnimap read 0k from imap.bang.priv.no (initial sync of 1 group; please wait)
Reading active file via nndraft...done
Reading active file via nnml...
Reading incoming mail from file...
nnml: Reading incoming mail (no new mail)...done
Reading active file via nnml...done
Checking new news...done

Two things of note here:
 1. It now apparently checks the cloud file automatically?
    That's new (for me)
 2. There are no lines of output for fetching with nntp
