After a .com domain has expired how long is it in quarantine?

Name Server: NS1.PENDINGRENEWALDELETION.COM
Name Server: NS2.PENDINGRENEWALDELETION.COM
Status: REGISTRAR-LOCK

If i go to the domain the NSI page says:
This domain name expired on 05/06/2006 and is pending renewal or deletion.


When can it be registered?
