Everytime a test gets stuck I see a whole bunch of threads from the
MINANetworkDriver.
Probably due to threads not being cleaned up properly in shutdown.
Best case this maybe due to a bug in the test, but in worst case this
maybe a bug in the MINANetworkDriver itself.
Therefore I think it's best to investigate this matter.
ex.
