Your guess is wrong.  "--restore" is more than that, and it is usually
much more efficient than starting over with the same parameters.

However, since you were getting forked processes not started or killed,
you did in fact have to start over not to miss any weak passwords.

"Remaining 25185227 password hashes" is low enough that you should be
able to run 40 processes now, if you skip the "single crack" mode as I
suggested.
