No, this is only if you want to pass some data to the application that you are
launching. If you just want to launch a normal app just pass NULL as the last
parameter to SysUIAppSwitch.
To answer the other question, YES you have to take care to delete the memory block you
did the MemHandleSetOwner on otherwise you will have a very big memory leak.
