Subject: * Enabled dead region tracking for ChildAgentDataUpdates ** If the
 region fails 3 times, then ChildAgentDataUpdates no longer get sent to that
 region * Enabled Child_Get_Tasks in grid mode. * When Child_Get_Tasks is
 enabled on neighbor regions, the neighbor region uses the client's draw
 distance to send out prim.   This is a lot less likely to flood the client
 now since the ChildAgentDataUpdate contains both the throttle settings and
 the draw distance.   This means that with this enabled, you can see prim in
 other regions in grid mode.   Very experimental.
