The quality here is well above average when it comes to code I've reviewed for this project.

I did not have time today to look at this as thoroughly as I would have liked and I may have missed important details.

Overall, I would like to see the log level dropped a little bit. There is an nvnc_trace() macro which I feel is underutilised.

Almost ready!

Okay! Tested most code paths with valgrind and fixed some refcount-based leaks.

@any1 : ready for another review!

LGTM after a few final tweaks.

@any1 Done!

Also fixed a handful of char *foo => char* foo we both missed :)
