[Linux] Hight CPU use when running Rebol server as a service

[Oldes]

Since version 3.11.0 starting Rebol web server as a service consumes almost all CPU... when running the same from command line is OK.
Having such a service file /etc/systemd/system/test-server.service

[Unit]
Description=Test simple Rebol server
After=network.target

[Service]
ExecStart=/usr/local/bin/rebol3 --do "import httpd serve-http [port: 8888 root: %/home/oldes/test/]"
Restart=always
User=oldes
Group=oldes

[Install]
WantedBy=multi-user.target

rebol3 --do "import httpd serve-http [port: 8888 root: %/home/oldes/test/]"

is OK:
