Thank you, Matthew.
The following code takes around 250ms on my machine. Any idea why? I was
expecting it to be fast since the module is based on racket/base.
#lang racket/base
(require syntax/location)
(require racket/place)
(module test racket/base
(provide place-main)
racket
(define (place-main pch)
(void)))
(time (place-wait (dynamic-place (quote-module-path test) 'place-main)))
