Using IronPython shell from GNU Emacs doesn't work

[programingfrik]

Prerequisites

Confirmed is an error not a question.

• Are you running the latest version?
• Are you reporting to the correct repository?
• Did you perform a cursory search?

Description

I'm triying to run IronPython 3.4.1 (ipy.exe) as my python interpreter inside GNU Emacs 28.2 (build 2, x86_64-w64-mingw32), but it doesn't work. The original cpython interpreter, from the cygwin package, does work, ironpython 3.0.0 from the mono project installer also works.

Steps to Reproduce

To reproduce this error:

1. Run GNU Emacs 28.2 having the python-mode 20221008.1936 installed.
2. Run the M-x customize command and search for the Python Shell Interpreter variable.
3. Put the ipy.exe full path on the variable and save it for the current session and future sessions.
4. Run the M-x run-python command to ask emacs for a python shell.

Expected behavior:

It should show the ironpython shell and let me work on it as an older version that comes from the mono project does:

Or as the cpython interpreter that comes from cygwin does:

Actual behavior:

Emacs tries to execute the interpreter but enters on some kind of infinite loop repeating "OSError: [Errno 9] The handle is invalid." until it is stopped either through the task manager or via the C-c C-c key combo:

Also i don't understand why emacs opens 2 sub-process of ironpython, maybe related to the error:

As I'm comparing against the ironpython 3.0.0 that comes with mono here I include the version:

Also I'm comparing against the cpython interpreter from cygwin, here I include the cygwin version:

$ uname -a
CYGWIN_NT-10.0-19044 DTI-6005-66 3.3.6-341.x86_64 2022-09-05 11:15 UTC x86_64 Cygwin

I think the error is probably the same as launching with the VS Code internal console.
