What version (or hash if on master) of pybind11 are you using?

2.10.0 (vcpkg)

Problem description

I'm producing a module that uses the date library
On c++ initialization (aka on import my_module) the module (and python) hangs since the library is trying to access some data using curl. Windows is blocked in "waitforsingleobject" and linux in "__GI___select", same behaviour.
If I disable the auto-check of tzdata the module works normally.

Anuy idea why python/pybind11 interacts badly with curl on init ?

Reproducible example code

I can submit a minimal example if needed.

Is this a regression? Put the last known working version here if it is.

Not a regression
