I have registered a method to the ContentService.Trashing event with:

ContentService.Trashing += ContentService_Trashing;

This in turn calls this method, which was written by someone else, and causes our application to hang. Here is a snippet of the method (which is a static method btw):

var oldCustomer = e.MoveInfoCollection.FirstOrDefault(x => x.Entity.ContentType.Alias == "Customerpage");
        if (oldCustomer != null)
        {
            // Delete role
            var roleName = oldCustomer.Entity.Name;
            var existing =
                ApplicationContext.Current.Services.MemberService.GetAllRoles().FirstOrDefault(x => x == roleName);
            if (existing != null)
            {
                ApplicationContext.Current.Services.MemberService.DeleteRole(roleName, true);
            }
            return;
        }

Is it a better way to do this than dragging in the memberservice (and then the same for media) to delete related content?

Should this be moved to some kind of scheduled task?
