Bug with coroutines?

["Thiago L." <fakedme@...>]

I was 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?
