Thank you very much!  I did a much more simplistic patch (basically 
commenting out restarting the xfrd child process after the first 
failure) and resperf reports 42k queries/sec (as opposed to 2k with all 
of the xfrd thrashing).  I tried your patch now, with the mmap flag as 
well, and now I am getting around 75k queries/sec!

Now if I can figure out why unbound is crashing due to malloc errors 
(which may be too aggressive tuning on my part), but that is a different 
list... ;-)
