Oh, this must be why my test had failed - I was using $2a$04 hashes
there.  I should have noticed that the c/s rate reported on the status
line matched the self-test's (it did), which means it was for $2a$05.

390000 clock cycles for $2a$05?  This feels too fast.  Maybe you meant
3900000 (twice faster than you had before)?
