No timeout between them, regular retransmission timeouts apply for each
attempt.

Who knows, legacy reasons maybe (on the other hand, the default is 1 now
with swanctl.conf).

Further traffic will trigger another acquire (it might even cause
duplicate SAs if a retry occurs while traffic triggers another acquire
from the kernel).
