OK, but this shouldn't be a problem with any applications currently
using close_stdout. At least, none of the applications I know about.

I can see the need for a module that does the trick you mention (with
suitable error handling) instead of closing stdout, for applications
that have nontrivial atexit handlers or destructors. This module's API
shouldn't use identifiers like "close_stdout", though, since they
wouldn't actually closing stdout.
