This is almost certainly the same issue as bug 36622 and bug 38200 (which aren't actually
mac specific, and the cause is believed to be well-understood). Assigning to me.

Evan's right that the problem is caused by subprocess, but it's not so much stdout buffering as it is the fact that we're using PIPEs with a fixed buffer size (even on windows), and overflowing the
buffer causes the threads to deadlock.
