Subject: * Implemented ChildAgentDataUpdate throttle multiplier based on an
 inaccurate count of neighbors. * The neighbor count is always lower then the
 actual number of neighbors unless your region was up the longest. * The
 region you're in is un-affected by this, though, you'll get less packet loss,
 maybe not get logged off immediately when you log in, and possibly see more
 prim if your internet connection is semi-unreliable.
