test.exe hangs on Appveyor CI
Tor's test.exe sometimes hangs on our Appveyor Windows CI.
I've seen this happen twice over the past few weeks. Here is one example: https://ci.appveyor.com/project/torproject/tor/builds/22791909/job/u0jd5tpr07mt2nv3
We've reduced the job time limit to 30 minutes to mitigate this issue. But I am not sure how to debug it further.
