I'm trying to receive messages from a place. Receiving the messages with
`place-channel-get` works fine, but using `sync` blocks indefinitely. I want to
use `sync` instead of `place-channel-get` to check multiple channels
simultaneously for messages.
Below is an example that demonstrates the problem. What am I doing wrong? Am I
using `sync` incorrectly? Does `sync` not work with channels?
(module hello-world racket
(require racket/place/distributed racket/place)
(provide world)
(define (world ch)
(define s (place-channel-get ch))
(place-channel-put ch (string-append s "World!\n")))
(module+ main
(define nd (create-place-node "localhost" #:listen-port 1234))
(define ch (dynamic-place #:at nd (quote-module-path "..") 'world))
(place-channel-put ch "Hello ")
; (define rs (place-channel-get ch)) ; works
(define rs (sync ch)) ; block indefinitely
(write-string rs)))
