How often does this happen in real life? I should think and hope that
real controllers can space aircraft better so that it's rarely
necessary to abort a landing.

In a few hundred hours flying out of Hanscom (primary GA field for
Boston) I've had to go around maybe a half-dozen times, mostly for
runway-lingering by the plane in front. Once the controller sequenced
me a little too tightly. It is a very busy field on the weekends with a
lot of training to keep things messy- 5th in line to take off or land
is not unusual.

In about a half-million airline miles, mostly continental US, I've had
one go-around, on the Delta Shuttle into Boston, because the plane
ahead had not cleared the runway in time. It was a CAVU day and I'd
guess we were well inside the middle marker when they threw in the
towel.
