10e6dadfe63181edabc58c8f42e3c56a1cd9ec95brendan# 1. A change to the ip stack breaking expected probe behavior,
10e6dadfe63181edabc58c8f42e3c56a1cd9ec95brendan# which is the reason we are testing.
10e6dadfe63181edabc58c8f42e3c56a1cd9ec95brendan# 2. No physical network interface is plumbed and up.
10e6dadfe63181edabc58c8f42e3c56a1cd9ec95brendan# 3. No other hosts on this subnet are reachable and listening on ssh.
10e6dadfe63181edabc58c8f42e3c56a1cd9ec95brendan# 4. An unlikely race causes the unlocked global send/receive
10e6dadfe63181edabc58c8f42e3c56a1cd9ec95brendan# variables to be corrupted.
