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.
>From any other window (see above) 
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) {
  if (!fork()) {
    if (i == 1) {
    if (i == 2) {

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

Good luck.
