New OpenSSH - strange processlist

Hi all, i noticed that 2 sshd's are running per login?! Szenario: no one logged in: 1 sshd (main) running. 1 user logged in: 1 sshd (main), 1 sshd (owner root), 1 sshd (owner user) running. 2 users logged in: 1 sshd (main), 2 sshd (owner root), 2 sshd (owner user) running. anybody knows why? afaik it wasn't so befor the update... Greetings, Sven
