A-HA!  FloatArray>>-=  now calls a primitive in FloatArrayPlugin that 
must be broken.  I removed the primitive call, and it now works correctly.

I checked to see if the plugin code in the Croquet image had been updated,
since I had built the VM based on a regular Squeak image.  I was somewhat
surprised to find that FloatArrayPlugin doesn't appear to be modified.

Even though I've scratched my immediate itch, I'm still curious about
getting to the bottom of this, so I'll poke around a bit more.
