One of the three, at least, will be in use for take-off only. It
ought to be possible for the aircraft on the middle runway approach
to turn towards that other runway and do a circuit in that
direction.

However at LHR the proposed third runway is a short one, and so
presumably will be used by smaller aircraft for both landings and
take-off.

Two outside runways have simultaneous take offs - I very much doubt
they will be turning towards one another, therefore the landing on
the center can go straight on!

We're not talking about a landing, but the need to "go round again"
if the landing has to be aborted. This is unlikely to happen later
than when the captain calls finals, when he will be a couple of miles
away from the threshold, at least. Consequently he can make a turn
without conflicting with the traffic taking off from the other
runways.

That is complete tosh. Most go arounds happen with a few feet of touchdown.
If the preceding aircraft is slow off the runway then the next aircraft may
start the go-around actually over the end of the runway.

In bad weather, a pilot may start a go-around at 50ft!
