Bug

What is the current behavior?
When I'm enabling Daemonizer "Daemonizer(cherrypy.engine).subscribe()", I see the log files permissions are changing to -rw-rw-rw- on rollover.
When I start the server, the log files are created with -rw-r----- but with roll over based on time, the new rollover files gets file permission as -rw-rw-rw-.
When I do not enable Daemonizer, I do not see any change in file permission on rollover.

If the current behavior is a bug, please provide the steps to reproduce and if possible a screenshots and logs of the problem. If you can, show us your code.
The steps are easy to reproduce. Adding Daemonizer to a log rollover server should reproduce the issue.
Will share the sample program if needed.

What is the expected behavior?
No.

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

That's interesting... I don't see this being done explicitly @ https://github.com/cherrypy/cherrypy/blob/6387a2b/cherrypy/process/plugins.py#L337-L424.

Perhaps a full repro would be helpful.
