Between a move constructor and QSharedDataPointer, I'd rather stay with the 
latter. It avoids the manual reference counting, which may include subtle 
errors.

An alternative is to use C++11 extern template declarations alongside an 
export macro. It's a solution I had tried and worked in 
QDBusUnixFileDescriptor, using GCC's equivalent C++98 extension.
