shell freezes on network activity / pip, brew download #1602
Description
I encountered the issue that when downloading packages, either in pip or homebrew, the shell freezes and i have to kill it.
Not sure what the exact trigger is, as networking overall seems to work fine (e.g. pinging google.com), also the installation of brew worked fine. However, every time i try to install a package with either one of brew or pip the shell freezes and doesn't respond on CTRL+C anymore.
With brew it usually happens after some packages downloaded successful:
Darling [/Volumes/SystemRoot/home/user]$ brew install python@3.13

While if i install Python 3.12 or Python 3.13 from the python.org .pkg binaries, and try to install any package with pip (with and without venv) the shell freezes instantly:
Darling [/Volumes/SystemRoot/home/electrum]$ python3 --version
Python 3.12.7
Darling [/Volumes/SystemRoot/home/electrum]$ python3 -m pip --version
pip 24.2 from /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/pip (python 3.12)
Darling [/Volumes/SystemRoot/home/electrum]$ python3 -m pip install requests
^C^C^C (no progress anymore)
I tried multiple ways to get pip and brew packages installed, and compiled commit 5faf581 on two different hosts (Fedora 42 and Ubuntu 24.04 LTS), the outcome is always the same. I tried the full build as well as DTARGET_i386=OFF. So maybe the reason is some underlying issue with Darling?
