QGlobalStatic (the hidden class behind Q_GLOBAL_STATIC) deletes the object
when the library unloads and sets the pointer to 0. Of course, since it's
static, it's rather pointless, because the library is being deleted --
it's just for the cases where the function gets accessed after deletion.
In those cases, the caller must be able to detect a 0 pointer. I am sure
99% of the code don't do that. In KStaticDeleter too.
Note that not all systems will call destructors in the event of library
unloading -- especially if they were loaded due to a plugin load.
