> Could you please test if additional SIGCHLD can release hanging?

Start mintty and check the process from another bash.

$ ps
PID PPID PGID WINPID TTY UID STIME COMMAND
1713 1662 1713 6800 cons0 197609 04:26:01 /usr/bin/ps
1671 1 1671 6072 ? 197609 04:25:47 /usr/bin/mintty
I 1672 1671 1672 2096 pty0 197609 04:25:48 /usr/bin/zsh
1662 1 1662 4696 cons0 197609 04:24:21 /usr/bin/bash

After typing enter into zsh several times, the prompt is not returned.

$ ps
PID PPID PGID WINPID TTY UID STIME COMMAND
1728 1727 1672 3948 pty0 197609 04:26:10 /usr/bin/zsh

1727 1672 1672 4076 pty0 197609 04:26:10 /usr/bin/zsh
1671 1 1671 6072 ? 197609 04:25:47 /usr/bin/mintty
1672 1671 1672 2096 pty0 197609 04:25:48 /usr/bin/zsh
1662 1 1662 4696 cons0 197609 04:24:21 /usr/bin/bash

SIGCHLD is sent to zsh with mintty as parent, but nothing seems to change.

$ kill -CHLD 1672
$ ps
PID PPID PGID WINPID TTY UID STIME COMMAND
1728 1727 1672 3948 pty0 197609 04:26:10 /usr/bin/zsh
1727 1672 1672 4076 pty0 197609 04:26:10 /usr/bin/zsh
1671 1 1671 6072 ? 197609 04:25:47 /usr/bin/mintty
1672 1671 1672 2096 pty0 197609 04:25:48 /usr/bin/zsh
1733 1662 1733 5388 cons0 197609 04:33:39 /usr/bin/ps
1662 1 1662 4696 cons0 197609 04:24:21 /usr/bin/bash

If SIGKILL is accepted, zsh will exit with mintty, but zsh's
descendant processes will remain.

> Are any additional settings necessary?

- zsh is specified by the environment variable SHELL.
- HOME is a symbolic link. (`/home/myname` -> `/cygdrive/c/Users/myname`)
- My cygwin environment is arm64 (M1 MacBook Pro). Windows is
installed on UTM. ( https://mac.getutm.app/ )
- Since I have several packages that I built myself, they may be
causing the problem.
