This is just AMAZING!!! I have wished for it for many years for DPDK, ever 
since I used it in beta before it went GA.

Would it be possible to post your modification of Valgrind in Github, 
Bitbucket, or some other repo? I'd like to try this out on my app, too.

Also, not sure if anybody sent this upstream to Valgrind, but if not, we 
really should, so it just works by default from now on.
