We were cleared to taxi to runway 9 via taxiway a, taxiway south, hold short of runway 4L.' we stopped late at the approach end of runway 4L (nose of aircraft over runway edge line) causing another aircraft to go around. Bos tower immediately saw this and called the go around -- good job boston! Contributing factors: busy airport, busy within cockpit doing the after start, taxi, and before takeoff checklists. Approach end of runway 4L and runway 9 very close.
