And the answer is...

Host B will retransmit the SYN upon time out since host A never sends an
ACK accounting for host B's SYN. THe SYN is considered part of the
sequence space and has to be handled like any other byte of unacknowledged
data. You might want to see the TCP mill std (mil-std-1778) pgs 151 and 152
which shows some of the hair you need to consider when retransmitting
SYNs. Mike

(Oh yeah, proper behavior for Host B when it recieves a duplicate SYN
is to reply with an ACK segment and drop the incoming, duplicate SYN)
