1) Use a small test program to validate that when no timers are set
and you pass in to the new logic TH_RST/TH_FIN or TH_SYN you
will correctly return true to pass the kassert
2) place the change in nf and test (which may or may not hit the problem)
since its a very rare event (the test prog is better to make sure we are doing the right thing) :)
