tasks running at different priorities. The downside is that the task only gets a
shared reference (`&-`) to the resource, limiting the operations it can perform
on it, but where a shared reference is enough this approach reduces the number

of required locks. In addition to simple immutable data, this shared access can
be useful where the resource type safely implements interior mutability, with
appropriate locking or atomic operations of its own.
Note that in this release of RTIC it is not possible to request both exclusive
access (`&mut-`) and shared access (`&-`) to the *same* resource from different
