14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 1. A change to the ip stack breaking expected probe behavior,
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# which is the reason we are testing.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 2. No physical network interface is plumbed and up.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 3. No other hosts on this subnet are reachable and listening on rpcbind.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 4. An unlikely race causes the unlocked global send/receive
