## Multithreaded updates
The same strategy won't work in the current multi-threaded version,
because the mutable reference would have to be sent over a channel. The borrow checker would
stop us, because `&mut Ticket` doesn't satisfy the `'static` lifetime requirement of `SyncSender::send`.
The same strategy won't work in the current multithreaded version. The borrow checker would

they can't be captured by the closure that gets passed to `std::thread::spawn`.
There are a few ways to work around this limitation. We'll explore a few of them in the following exercises.
