... or maybe the parent thread should not exit immediately but wait:
   if (daemonize && !isatty(0)) {
#include <sys/wait.h>
     int status;
     int pid = fork();
     if (pid > 0) {
       waitpid(pid, &status, 0);
       exit(0);
     }
     setsid();
   }

Can you please try both alternatives?
Thomas
