[Xastir] NTP bug causing high CPU load (Linux, maybe other Unices)

[Curt, WE7U]

I was experiencing VERY high CPU load, mostly system CPU usage, from my 
mythtvbackend daemon.  It started yesterday or perhaps even the day before. 
Firefox was also causing very high CPU load but only for 30-45 seconds on a 
periodic basis.  Mythtvbackend's CPU usage was continous, causing a CPU load of 
20 - 25!  That makes the system somewhat unresponsive.

The fix turned out to be killing/restarting NTPD.  It seems a leap-second was 
added recently which threw NTP for a loop.  Others may be experiencing similar. 
Kill/restart that daemon.  It's a hard one to track down from system 
monitoring.  I found the root cause via some Google searches this morning.
