playing around with coroutines and I think I found a bug
when interrupting a running coroutine.
(I'm on windows so I'm gonna be using ctrl+c for the
interrupt key, so it might not work for everyone)
When doing coroutines:
Lua 5.2.3 Copyright (C) 1994-2013 Lua.org, PUC-Rio
> =coroutine.resume(coroutine.create(function() while
true do end end))
[hit ctrl+C here]
When doing pcall:
Lua 5.2.3 Copyright (C) 1994-2013 Lua.org, PUC-Rio
> =pcall(function() while true do end end)
[hit ctrl+C here]
false interrupted!

So is this a bug or am I missing something?
The second case is straightforward. pcall fails because
Lua was interrupted.
I believe that this is a case of who is receiving the
interrupt. L receives it, and closes L and collects all
garbage, including the coroutine, which never *really*
closed. The main thread is what is shut down.
I'm probably being imprecise, but that's how i
understand it.

It actually waits until the coroutine dies to process the
interrupt... and either way it's still a bug...
