Emacs doesn't know when the system starts swapping.  But you can write
a function that tracks the vsize of the Emacs process, using emacs-pid
and process-attributes, and displays some prominent message when the
vsize increments become larger than some threshold, or the vsize
itself becomes larger than some fixed number.  Then run this function
off a timer that fires every 10 or 15 seconds, and wait for it to tell
you when the fun starts.
