I was reading through the docs and came across a section that felt awkward.
I've tried to improve the flow by splitting up and reversing the explanations of
Arc and Mutex with some example code in between.
The "This would have have happened" bit is unfortunate but I couldn't see any
other way to illustrate it. The compiler errors didn't really help tell the
story in this particular instance so it still feels a bit forced. However I do think it's
an a small improvement...
Does anyone have any other ideas that might flow better?
