20001014: attempt to close protected handle

Zsh regression tests that used pty's started to hang since one of post-1.1.4
snapshots (they did not work in 1.1.4 at all due to pty bug). I finally got a
closer look at it and found interesting thing.
Chris, you said, you use Zsh. I hope, you won't mind to compile it - it does
it OOTB.
The following happens with current Zsh CVS; it may happen with 3.1.9-dev-6
(the last released version) as well, but I have not tested it. cygwin-20001014
snapshot. Look at http://www.zsh.org or http://sourceforge.net/projects/zsh
for Zsh sources.
Compile Zsh; no special configure options are needed; I use --prefix=/usr.
Run it; I use direct shortcut to zsh and put path=(/usr/bin /usr/local/bin
$path) in /etc/zshrc. You may even run it as 'c:\cygwin\bin -f' to get clean
state.
Then execute:
MW1G17C% zmodload zsh/zpty
MW1G17C% zpty zsh zsh -f
MW1G17C% zpty -d zsh
0 [main] zsh 1868 close_handle: attempt to close protected handle int
proc_subproc (long unsigned int, long unsigned int):289(childhProc<0x180>)
2567 [main] zsh 1868 close_handle: by int fhandler_pty_master::close
():912(get_ttyp ()->to_slave<0x180>)
MW1G17C%
To comment: zpty allocates pseudo-tty and starts command attached to this pty.
It assigns it handle `zsh'. zpty -d tries to kill associated command by
sending it HUP.
I CANNOT reproduce it with strace. Simply starting 'strace -ozsh.strace
zsh -f' hangs forever. If you may point to a bug in zsh that causes it - you
are welcome.
In the following cygcheck cygwin1.dll is listed twice - because I started zsh
via run and cwd was c:\cygwin\bin
All this does not happen with stock 1.1.4. It did not happen in at least some
post-1.1.4 code (I specifically tested it to see if pty bug was fixed).
It may or may not be related to bash exiting problem.

Have a nice DOS!
