It's bad.
It creates a lot of unneeded overhead.
As long as the control is csloading, csdestroying or not becomes visible
a Handle is not needed and should not be created.

Use 'if csLoading in ComponentState' to find out if it is still
loading. Loading is finished when 'procedure Loaded;' is called. You
can override that.
