Contradiction in section 7.11

[xiorcale]

In section 7.11 Locks, Send and Arc, it seems that the text contradict itself. First in the section "Who holds the lock?" it says:

We can't send a Mutex over a channel, because Mutex is not Clone

However, a bit below in the section "Our challenges", it says:

We can send a Mutex over a channel because it's Send

That's confusing and I'm not sure if we can send a mutex over a channel or not after all.

I think there is a typo and you are right.

[iurii-kyrylenko]

We can't send a Mutex over a channel, because Mutex is not Clone.

I think it means: We can't send a Mutex as an owned value over a channel, because Mutex is not Clone.

How about:

...
We can’t send the Mutex<Ticket> value over a channel because it's in the TicketStore entry: we shouldn't move it out and we can't Mutex is not Clone either. Could we send the MutexGuard instead?
