Subject: [PATCH] CVE-2025-40909: Clone dirhandles without fchdir
This uses fdopendir and dup to dirhandles. This means it won't change
working directory during thread cloning, which prevents race conditions
that can happen if a third thread is active at the same time.
Backport commit 918bfff86ca8d6d4e4ec5b30994451e0bd74aba9
