I would like it if this had a ScheduleManage and Manage, and that the
ScheduleManage used a postTask technique to actually schedule a manage call.

e.g. 
  manage_scheduled_ = false;
And
  if (!manage_scheduled_)
  MessageLoop::current()->PostTask(
      FROM_HERE, base::Bind(&GpuMemorYManager::manage, this));

Done.
