Qt is not STL nor does purport to replace it completely. There are many 
features in STL that are not in Qt and also vice-versa: many features in Qt 
tool classes not present in STL.

Qt tool classes do not support custom allocators. That feature cannot be added 
until Qt 5, so any discussion is tabled for now.

In any case, QVector<T>::Data contains one element of type T. I suggest using 
compiler extensions to change the alignment of said type, like GCC's 
__attribute__((aligned(N))).
