Are you using passwd/pam combination? The second process is "auth
worker", which does blocking passdb/userdb lookups. The v1.0 behavior
was causing bugs.

Currently there's no way to avoid that, except if you switch from PAM to
e.g. shadow. v2.0 stops idling processes after a minute (but there are a
some other new long running processes, and also it looks like that
idle-stopping isn't currently working for some reason).

That won't help anyway. You'd still have the same processes.
