PEP: 433 Title: Add cloexec argument to functions creating file descriptors Status: Draft The PEP is still a draft. I'm sending it to python-dev to get a first review. The main question is the choice between the 3 different options: * don't set close-on-exec flag by default * always set close-on-exec flag * add sys.setdefaultcloexec() to leave the choice to the application Victor Nice clear explanation.

I think io, meaning _io and _pyio really, would be amongst the impacted modules, and should perhaps be in the examples. (I am currently working on the Jython implementation of the _io module.) It seems to me that io.open, and probably all the constructors, such as _io.FileIO, would need the extra information as a mode or a boolean argument like closefd. This may be a factor in your choice above.

Other things I noticed were minor, and I infer that they should wait until principles are settled.
