This is usually because you have lots of salts loaded and a slow format 
(you'd only get a reaction once all salts are processed) but in this 
case there's only one salt so I'm not sure what happens.

I just tried this:

$ ./john -form:phpass --list=format-tests | cut -f3 >
$ ./john -form:phpass-cuda -progress-every=1
Loaded 16 password hashes with 14 different salts (phpass-cuda [MD5 CUDA])
Press 'q' or Ctrl-C to abort, almost any other key for status

BTW there's no temp/fan readings at all here because this is a Macbook 
and for some reason NVML is not available :(
