In that context it can only become unsafe (under the assumption that
starting the thread after the constructor would be considered safe) when a
subclass is involved. Else for all other intents and purposes the start()
can be considered to have occurred after the constructor completed.

Tests to prove the presence of a race condition are notoriously difficult to
write and impossible to write reliably.
