This brings up an interesting question: Who has the right of way? Me,
because I am already on the runway, ready to take off - or the traffic
on approach, because it was "landing" (though had not so stated - only
an "IFR Approach" called out). As it
turned out, I held at the departure end, and the traffic declared a
missed approach (perhaps having intended to do so all along?), and
passed overhead.

How close was he? If he's a few miles out you have no conflict,
takeoff and turn.
