Actually cpgbench doesn't show the overhead, as it uses CS_DISPATCH_BLOCKING. After
changing the following in cpgbench.c:

-       cpg_dispatch (handle, CS_DISPATCH_BLOCKING);
+       while(1) cpg_dispatch (handle, CS_DISPATCH_ONE);

I'm getting mixed results (worse for 64 bytes, better but unstable for 8k
and 40k). I'll investigate further and let you know.
