Yes, that works fine now, as does bash -c inetd.
However when I launch inetd from an rxvt window running bash, or
from a Dos window running cygwin.bat with tty, I still see tty handles
CYGWIN_ME-4.90 hpn5170x 1.5.6(0.108/3/2) 2003-12-27 17:25 i686 unknown unknown Cygwin
I ran strace -o trace rxvt -d :0 -e bash
followed by inetd in the rxvt window.
The trace, available on http://mysite.verizon.net/phumblet/trace,
shows that the usecount is off by one.
Correct run (bash -c inetd):
159 220557 [main] inetd 34889607 setsid: sid 34889607, pgid 34889607, ctty -1, open_fhs 3
168 220725 [main] inetd 34889607 fhandler_tty_slave::close: /dev/tty2 closed, decremented open_fhs 2, usecount 2
Incorrect run (under rxvt)
167 88587 [main] inetd 34937947 setsid: sid 34937947, pgid 34937947, ctty -1, open_fhs 3
159 88746 [main] inetd 34937947 fhandler_tty_slave::close: /dev/tty2 closed, decremented open_fhs 2, usecount 3
