I used top a bit during the run, and there's a screenshot of the Mac  
OS X system monitoring GUI application at the previously posted URL.   
Both show a 60-70% idle CPU with no paging or other issues.  (The  
machine has a substantial amount of RAM.)

I don't think anything is out of line:

$ erl
Erlang (BEAM) emulator version 5.6 [source] [smp:8] [async-threads:0]  
[hipe] [kernel-poll:false]

I did try some different build configurations without getting  
significantly different results.
