  Don't forget to retain the subviews. Adding a view to a superview 
retains it, and removing it again releases it, so if you want to 
remove a subview from one view and add it to another, you may want to 
[[myView retain] autorelease] it to make sure it doesn't get disposed 
before you've re-added it.

  All that is of course is only necessary if you haven't otherwise 
retained the view already, and only if you're running non-GC.
