[racket] Racket Virtual Machine runs out of memory

I took Matthias's test, compiled it from DrRacket "create executable"
option and ran it on my machine: Inspiron 1525 3Gbyte dual core about
6 years old.

#lang racket
(define l (time (build-list (* 4091 5023) (λ (x) 1))))
(system "PAUSE")

WORKS

#lang racket
(define l (time (build-list (* 7091 5023) (λ (x) 1))))
(system "PAUSE")

ABORTS with Racket Virtual Machine run out of memory

Thanks,
Harry
