INIT_CWND comes into play during any restart, e.g., after a gap in the 
offered load.

While I don't expect LEDBAD would be used primarily for shortlived flows:
	1) we can't know that, so should plan accordingly
	2) long-lived flows with frequent gaps do exist, and
	should not cause a problem either
