Sorry but no it's the opposite. A server has no issue with knowing that
a SYN belongs to a new session by seeing its ISN greater than the end
of the previous window. On the opposite, a client cannot know if the
remote server it wants to connect to is safe for reuse and will refrain
from establishing a new connection during the whole TIME_WAIT state,
effectively preventing itself from doing its job.

Willy
