 No, it doesn't. It uses pause(3).
 
 The problem can also be reproduced with cron(8):
 
 tron@lyssa:/#/etc/rc.d/cron restart
 Stopping cron.
 Waiting for PIDS: 268, 268, 268, 268, 268, 268, 268, 268, 268, 268, 268, 268, 
268, 268, 268, 268, 268, 268^Z
 zsh: suspended  /etc/rc.d/cron restart
 tron@lyssa:/#pkill -9 cron
 tron@lyssa:/#fg

 .
 Starting cron.
 
        Kind regards
