/**

* Get the number of seconds the user has been idle. In Unix-world

* this is based on the X Windows usage. In MS Windows this is

* based on keyboard/mouse usage information obtained from the OS.

* In MacOS X, this is based on keyboard/mouse usage information

* obtained from the OS, if configure detected IOKit. Otherwise,

* MacOS X is handled as a case of X Windows.

* In Debian bug #271639, jwz says:

* Purple should simply ask xscreensaver how long the user has been idle:

* % xscreensaver-command -time

* XScreenSaver 4.18: screen blanked since Tue Sep 14 14:10:45 2004

* Or you can monitor the _SCREENSAVER_STATUS property on root window #0.

* Element 0 is the status (0, BLANK, LOCK), element 1 is the time_t since

* the last state change, and subsequent elements are which hack is running

* on the various screens:

* % xprop -f _SCREENSAVER_STATUS 32ac -root _SCREENSAVER_STATUS

* _SCREENSAVER_STATUS(INTEGER) = BLANK, 1095196626, 10, 237

* See watch() in xscreensaver/driver/xscreensaver-command.c.

* @return The number of seconds the user has been idle.
