Lots of architectures and OSes have dealt with NUMA for a long time; 
Solaris deals with this really well (on SPARC, if not x86_64); this is 
my first experience of NUMA under Linux (any arch); RHEL5's 2.6.18 
kernel seems rather outdated, it seems the Linux kernel has moved on in 
the last few years; I'm looking forward to testing this OS and app with 
a newer kernel next week, should be informative...
