   I can answer to that one - it won't happen, basically ever.  Qt4 won't have 
it, and Qt 4 will last the next 3 years or so, and based on what Trolltech 
engineers told me, they won't attempt this for any other future release.  
Note that they don't even do this on PDAs or phones, where memory constraints 
are realistic.  Even if Qt had it, which it won't, KDE won't.

   This debate has come up in the past with KDE, and I'm surprised we don't 
have a FAQ entry on it yet.  We do have one on "if (ptr) delete ptr;":
