No. If it is there, then it should work. If it doesn't, then ask Guido
what he'd like to do. His answer will be one of:

1) it should be removed for that platform
2) it will stay; test sys.platform to determine whether it will work.

There is no reason for anything to code defensively against the standard
distribution library. There is no need to second-guess all of its
modules and functions.

[trimming the rest of this email note]

Can you send around a URL to the interscript online doc? And when you
refer to it, could you please cite a more specific reference? Call it a
character flaw, but I'm not going to just blindly go read a bunch of
doc. A concrete reference helps (me, at least) provide some
focus/structure to why I'm there reading the thing in the first place.
