@pmuellr , It's because `Error.prepareStackTrace` is global scope.
when I integrate `weinre` in my project, some awful happens in my OWN
program and cause a
connect error:
```
"Error: connect ECONNREFUSED 127.0.0.1:80
at Object.exports._errnoException (util.js:874:11)
at exports._exceptionWithHostPort (util.js:897:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1063:14)"
```
then the code `Error.prepareStackTrace` will called.
**utils.js**
```
Line 176 func = callSite.getFunction(); // func = undefined
```
It's not fair to blame this bug to `weinre`, but It's effect my program
indeed.
Any good advice?
