I'm actually running the HEAD version now, but my problems still 
persist.  I did notice that the excessive load is now spread across 
multiple cores where before it was isolated to one core at a time.  This 
version also doesn't suffer from the horrible performance I experienced 
with v2.2.5.

Thanks,
