That is odd, I also find it odd that it deadlocks the entire python
system, even threads that have nothing to do with the subprocess stop
working, the entire thing just stops. I may not have pasted the full
stack trace looking at it again, I'll double check in a few.

I was able to repro this on a tool I have the source for, when I
attach to it to debug visual studio tells me the threads are
deadlocked and the only stack trace I have available to me is a low
level os call to a WriteFile function.
