I played a bit around and tried to install severall python packages.
There seems to be a severe issue, because an increasing number of python
packages need a working rust compiler to build. And AFAIK there is no
rust compiler for cygwin at the moment.

I'm seeing reproducible (for me) hangs with the test Python 3.12
packages under Cygwin 3.5.4.
First, I see a hang doing `python312 -m pip install ipython` in a venv.
ipython is a too large package with too many dependencies.
Not a good test case.
I will build some more 3.12 modules for that scoepe
The hang occurs during downloading. If the package is already downloaded
it doesn't hang. So I'm doing a `pip cache purge` to get it to reoccur.
It usually hangs on downloading Jedi which is a large-ish module.
Downloading jedi-0.19.2-py2.py3-none-any.whl (1.6 MB)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 0.0/1.6 MB ? eta -:--:--
1.6 Mb does not seem a large load
Steps I'm taking are:
# clean up from previous runs
rm -rf /srv/pyvenvs/py312
pip3 cache purge
# Create a venv in an empty directory
python3.12 -m venv --system-site-packages --without-pip /srv/pyvenvs/
py312
(The --without-pip is needed because it fails without it running `-m
ensurepip`
It is looking for the pip wheel but not finding it.)
$ python3.9 -m ensurepip --version
pip 19.2.3
$ python3.12 -m ensurepip --version
pip 24.3.1
$ python3.12 -m pip --version
pip 24.3.1 from /usr/lib/python3.12/site-packages/pip (python 3.12)
what is coming from your system ?
