This leaves a GC-collectible allocation in C land. For `puts`, it's

That's what I'm referring to in the conclusion where I say this about
what's going to be in Part Two:
how to avoid a potential problem spot that can arise when passing
GC-allocated D strings to C
I'll cover approaches to maintaining a reference, like `GC.addRoot`, and
emphasize that it applies to any GC-allocated memory, not just strings.
OK, I'm just concerned people will see the pattern:
```d
somecfunc(str.toStringz);
```
and think that's the end of it.
