@joyeecheung I don't suppose you got anywhere looking at #12433, did you? This issue would seem to suggest that it's a problem in run.js itself or something like that and not at all a problem in the http test double.

The null probably originates as NaN and gets stringified when process.send() is called, resulting in null. /cc @joyeecheung

EDIT: Oh, or perhaps more likely, Infinity instead of NaN.

[joyeecheung]

@Trott I got stuck because I didn't think of the NaN/Infinity -> null thing..thanks for figuring this one out!
