FWIW I recently found that starting from CentOS 7.5, gsd-account/polkitd 
have been constantly using 10%-15% CPU.

I dug it a little bit yesterday and found the cause:
https://bugzilla.redhat.com/show_bug.cgi?id=1600161#c3

Workaround is to disable account password expiration check by removing
/etc/xdg/autostart/org.gnome.SettingsDaemon.Account.desktop

If you are switching too/using GNOME3 and see high CPU usage. This might 
be a cause.
