Yes, I remember that, that's because I was sceptic when started with changes 
about deffered deletion.
1.Only two objects have problems with postponed destroying TQtTimer & TQtMenu 
(TPopupMenu exactly).
Those objects have problems cause inside their events we call LCL directly.
2.Another one which could be problematic (theoreticaly) is TQtComboBox with 
call to IntfGetItems inside it's event filter. But at this moment my tests 
say that it does not raise any problem.

Now I'm sure that this is the right way, because it really works better and 
faster (apps & ide).
I'll commit it with USE_QT_44 ifdef.
