I think I get the picture.  Please correct me if I'm wrong.
If Fedora ever touches the swap file, once it has allocated the requisite
amount of it, and finished using it, the OS will not imeediately
deallocate the swapfile but rather it would lie in wait  till there's
another process that will be needing it.  So I don't really need to worry
about the condition.  The only time I'll get worried is when disk swapping
happens often, indicating that real memory is not enough.
