KConfigGroup automatic sync

[Sebastian Trüg]

The techbase article on KConfig states that the KConfigGroup destructor will 
sync automatically:

"We can also simply wait for the object to be destroyed, which triggers an 
automatic sync() if necessary."

This is not the case. Question is: what is the preferred behaviour? Should it 
sync automatically or not? In the latter case, one would have to call sync 
whenever one uses a group for writing which is very annoying.

Cheers,
