Is there such a thing as a coverstitch that doesn't unravel?
The coverstitch produced by my Janome 900cp unravels if you break a thread. For active wear this is a bit of a problem.
On the other hand my 4 thread overlocker (which doesn't do a coverstitch) produces a stitch that is very difficult to unravel. Is there something like this for doing coverstitch?

Can't answer that, my Babylock coverstitch does definitely unravel if you pull on the looper stitch. I think it's the nature of the beast, the stitch is formed using a chain stitch. My instructions say to give the needle stitches a firm yank, then thread them into a sewing needle and poke them to the back side, where they are tied off to the looper thread. That works so far for me, but would not be a solution if your problem is caused by *broken threads* in the line of stitching.
Have you tried something stretchy, like wooly nylon, in the looper? And maybe even in the needles? Do you have differential feed? If so, you could test breaking point using different threads and differential-feed settings to see if some combination would work better for your application.
I think maybe you are comparing apples to oranges. My Huskylock 936 can be converted to do a coverstitch. I haven't tested it, but I doubt it forms the stitch differently than the Babylock CS. On the other hand, there are coverstitch machines which form the loops on both the top and the bottom, perhaps they are less likely to come undone(?), but I don't know if they are available for the home-sewing market.
