------------------------------+--------------------------------
 We should look into implementing the Rust `alloc::allocator::Alloc`
 [https://doc.rust-lang.org/stable/alloc/allocator/trait.Alloc.html trait]
 as a wrapper around `tor_malloc` as a way to have a cleaner allocator
 interface in Rust moving forward (which still works with our current
 legacy C code).

 This is what the Rust code in Firefox has done, and the `alloc` crate is
 supposed to stabilised "soon" (as in, within the next six months) because
 FF is using it.
