Anastasia, thanks for the patch, but the change being suggested here is adding the note about it not replace os.exec or os.fork.  The listing of what things it does replace is already correct (it differs between python2 and python3, which is why Anatoly's list has things in it that aren't in the python3 doc).

Personally I don't think that adding the note is useful.  The list of things subprocess doesn't replace is much less well defined than what it does replace.  I think we should just list the former, as we do.

So, I prefer going with removing 'such as', and treating it as a bug if there is something in the stdlib that subprocess should (normally) be used in place of that is not included in this list.
