(Archived) Why Deactivation is "Pending"

[Mario@NCI 2]

With Sponsored Groups, I am the administrator. I deactivated a member from my group. After clicking on "Deactivate", The Manage Membership screen says "Deactivation Pending". Why is it pending? I deactivate a member because I need that seat for someone else. I expect deactivation to be immediate. Why delays? Thanks.
