Removing dependency to the database code is trivial. It's just 100 lines 
that launch lots of threads and do NUMA-aware memory accesses so that 
remote NUMA access cost does not affect the benchmark.

It's just a bit tedious to convert the C++11 code into C/pthread.
C++11 really spoiled me.
Still, not much work. Let me know where to post the code.
