>From the thread in c.l.p:
Pros (of changing os.pipe() to return inheritable pipes):
- as it isn't explicitely documented whether os.pipe() returns
inheritable pipes or not, both versions are "right" according to the
documentation.
- if someone relies on pipes being non-inheritable on Windows (why?),
this is undocumented behaviour, and Python has the right to change it.
- would improve POSIX compatibility, it mimics what os.pipe()
does on those OS
- inheritable pipes are less surprising for guys coming from other OS
- inheritable pipes are a lot more useful than non-inheritable ones
when doing IPC (probably its main usage).
Cons:
- os.pipe has behaved that way since long time ago.
- some programs *might* break, if they relied on pipes being
non-inheritable on Windows, even if that was undocumented behaviour.
