Issue #22181 : On Linux, os.urandom() now uses the new getrandom() syscall if
...
available, syscall introduced in the Linux kernel 3.17. It is more reliable
and more secure, because it avoids the need of a file descriptor and waits
until the kernel has enough entropy.

Issue #23694 : Enhance _Py_open(), it now raises exceptions
...
* _Py_open() now raises exceptions on error. If open() fails, it raises an
OSError with the filename.
* _Py_open() now releases the GIL while calling open()
* Add _Py_open_noraise() when _Py_open() cannot be used because the GIL is not
held
