This looks more and more like PEP 433 :-)
I don't like the global modifiable default, for the reasons Charles Francois gave some months ago.
I did have time yet to rewrite the PEP 446, I'm writing first its implementation. Basically, the new PEP 446 is:
- functions creating file descriptors and Windows handle now clear the inheritable flag (disable inheritance by default)
- add new functions os.get/set_inheritable()
- subprocess makes fds of pass_fds inheritable
- (maybe) os.dup2(fd, fd2) makes fd2 inheritable for fd 0, 1, 2
That's all! No more new cloexec parameter to +15 functions and classes, no more global variable (default inheritavle values).
