release is indeed better. To me, "wipe" means zeroing out (possibly after
an optional number of passes writing trash to the memory area) rather than
actually freeing any memory.

Always having a compilable/operational tree is pretty nice primarily due
to bisect. If the code turns from working to non-working in between,
make sure to jot it down in the commit message.

It might even be better to add the embedded NUL handling code in the
first patch, modify the callers in the second, and remove the embedded
NUL handling in a third.
