I was doing some random other thing locally and noticed that there was some
weird issue with synchronization around the TorrentBroadcast lock (there is a
single shared lock used a bunch inside of that) a bunch of tasks were waiting
for the lock for a long time. Maybe somehow that is slowing things down the
tests as well.
