Rederer timeout

I've detected this problem with Jade templates.
Whenever i write something like:

``` jade
- var i = 0
while i < 10
p ...
```

In the moment I type the "p" the previewer freezes and closes after while.
I know it's a Jade problem and there they aren't working on this.
I just thought if atom-preview could have a timeout attribute to kill render processes after delayed time.
