Thanks for the review Bart! I did not make the arrays static because 
their entries depend on the runtime addr and val arguments. A shared 
static buffer would be racy if two callers ran concurrently. However, I 
can make the arrays const in v2 by moving the addr/val-derived bytes 
directly into the initializer.

Regards,
Larisa
