Curious.  I regularly check that swapoff is working (though not suspend
and resume), and have not noticed this.  You fill memory so the machine
swaps, let the memory hog exit, then swapoff hangs indefinitely (not just
taking a long time)?  With no suspend+resume since booting at all?

How much memory?  How much swap?  What .config?  I'll try it tomorrow.
