An erj-170; taking off; suffered an near midair collision with a commuter aircraft directed to go-around and turn left while on approach to an intersecting runway. The failure of the commuter flight crew to respond promptly to the turn was cited as a contributing factor.

Narrative:
We were cleared for takeoff off of 9L last night. During the takeoff roll; at about the 80 KT callout; we heard tower direct a commuter inbound to runway 17 to go around and turn to a 050 heading. About that time we were past V1 and the first officer had started to rotate when we both saw the commuter; still on the runway heading; just to our left. My first officer slowed our rotation to ensure sure we had adequate clearance with the plane now right above us. My best guess is that there was about 150 foot separation between the aircraft. Tower also directed us to make a right turn to 120 heading but we delayed the turn to ensure that we had adequate [vertical] clearance from the other aircraft. We were then handed off to departure.I believe it was both misjudgment on the timing of the ILS approach to runway 17 and our takeoff off from runway 9L; and the slow response of the commuter crew to make the turn that contributed to this close call. This has never happened to me before but better situational awareness of the tower or a quicker response by the other crew to make the immediate turn could have prevented this.
