Bug description:
On python 3.13 (Fedora), importing ctypes results in the following output from lsfd:
python3 893377 daandemeyer mem r-x--- REG 0:37 0 304862113 /usr/lib64/libffi.so.8.1.4
python3 893377 daandemeyer mem r----- REG 0:37 0 304862113 /usr/lib64/libffi.so.8.1.4
python3 893377 daandemeyer mem r----- REG 0:37 0 304862113 /usr/lib64/libffi.so.8.1.4
python3 893377 daandemeyer mem rw---- REG 0:37 0 304862113 /usr/lib64/libffi.so.8.1.4
On python 3.14 (Fedora), importing ctypes results in the following output from lsfd:
python3 892407 daandemeyer 5 r----- REG 0:238 1342 7553 /usr/lib64/libffi.so.8.2.0
This ended up breaking https://github.com/systemd/mkosi because it relied on the fact that no new regular file descriptors were opened by importing ctypes (on python 3.14 the file descriptor shows up in /proc/self/fd whereas on python 3.13 the file descriptors are memory maps which don't show up in /proc/self/fd). I searched through the commit list and couldn't find the commit that introduced this change. It also didn't seem to be documented in the release notes. Can anyone point me to the commit introducing this change and the reasoning behind it?
