In these cases access to Rust data structures inside the callbacks is
especially unsafe and proper synchronization mechanisms must be used.
Besides classical synchronization mechanisms like mutexes, one possibility in
Rust is to use channels (in `std::comm`) to forward data from the C thread
that invoked the callback into a Rust thread.

thread that invoked the callback into a Rust thread.
If an asynchronous callback targets a special object in the Rust address space
it is also absolutely necessary that no more callbacks are performed by the
