It looks like the logic for constraining supported versions is more liberal 
than I assumed, so I've added a note to UPDATING.  It is good practice to 
rebuild all modules between kernel updates on -CURRENT.

If anyone can reproduce the malloc-related *after* rebuilding all modules, 
please let me know, it could be an indication of a bug in kern_malloc.c.
