I can rewrite the PEP 446 to:

* make all file descriptors and handles non-inheritable
* remove the cloexec parameter
* remove everything about non-blocking sockets (O_NONBLOCK), it should
be discussed in a new PEP (it's no more related to O_CLOEXEC /
HANDLE_INHERIT_FLAG)

Should I rename os.set_cloexec(fd, cloexec) to os.set_inheritable(fd,
inheritable), and os.get_cloexec(fd) to os.get_inheritable(fd)?

Or do you prefer a simple os.make_inheritable(fd) with no inheritable
parameter? I prefer an explicit parameter, so it's also possible to
force again non-inheritable, which also makes sense if the file
descriptor was not created by Python.
