Sorry Chris, it's not automated and it relies on repeating the same
test in many different conditions, in particular from 
 cmd.exe with CYGWIN=tty or not, 
 cygwin console, notty (sh & bash), 
 cygwin tty (sh & bash)
 rxvt (sh & bash)

1) In any window (see above)
setsid sleep 10
should return immdiately.

2)  Create a tty window, say tty1.

setsid sh -c "echo hello > /dev/tty1; /bin/sleep 10; /bin/echo there > /dev/tty"
and repeat with bash.

Should return immediately
Use ps to see that sleep has ctty 1
Verify "hello there" output on tty1

3) In any window (see above)
the following program should go in the background
when given argument 0, 1 or 2

#include <unistd.h>
#include <signal.h>

main(int argc, char * argv[])
{
  int i;
  signal(SIGHUP, SIG_IGN);
  i = atoi(argv[1]);

  if (i == 0) {
    close(0);
    close(1);
    close(2);
  }
  if (!fork()) {
    if (i == 1) {
      close(0);
      close(1);
      close(2);
    }
    setsid();
    if (i == 2) {
      close(0);
      close(1);
      close(2);
    }
    sleep(10);
  }
}

I used to also test inetd on 9x but I think it's
covered by test #3 

Good luck.

Pierre
