Yes, the full ETA and stats summary, including GPU and fan if the

Hmm. It happens to me with a single salt, a CPU format, and no wordlist.
With a "busier" run like the one you describe, I've seen exactly the
same delays in status and ctrl-c, and they're understandable. This
issue seems different in kind.

Yes, SIGUSR1 also works. Interesting.
