Subject: [PATCH] Fix unused Box linter warning.

`cargo check` is not happy with original code
```
    = note: call `drop(Box::from_raw(ptr))` if you intend to drop the `Box`
    = note: `#[warn(unused_must_use)]` on by default
help: use `let _ = ...` to ignore the resulting value
    |
151 |             let _ = Box::from_raw(writing);
    |             +++++++
```
and adding `drop` is not only recommended but also makes the intent explicit.
