Thank you. I hope you can try the implementation and report feedback
on that too.

Hmm. I see that this would be a good idea. but it raises the question
of how to manage the set of file handles that should not be closed on
becoming a daemon.
So far, the logic of closing the file descriptors is a little complex:
* Close all open file descriptors. This excludes those listed in
the `files_preserve` attribute, and those that correspond to the
`stdin`, `stdout`, or `stderr` attributes.
Extending that by saying “… and also any file descriptors for
``logging.FileHandler`` objects” starts to make the description too
complex. I have a strong instinct that it the description is complex,
the design might be bad.
Can you suggest an alternative API that will ensure that all file
descriptors get closed *except* those that should not be closed?
