>> 'window-configuration-change-hook' is a quite expensive hook which is
>> run for way too many functions in the windows area.  It's expensive
>> because it's run for every single invocation of these functions and
>> often even if nothing had changed at all.  I plan to run it exclusively
>> for the following cases - window deletion and creation and displaying a
>> different buffer in a window - which are all real changes.  Any window
>> resizing is covered by ‘window-size-change-functions’ which is now run
>> (almost) only when the size of a window really changed.
>
> OK.

Closing this bug then.

Thanks, martin
