        sys/kern/kern_descrip.c: revision 1.185
- Fix a bug where we trashed descriptor zero in the old open files array
  while ironically trying to preserve the same during copy. Would only have
  occurred if a multithreaded program expanded the descriptor table and,
  within a tiny window of exposure, another thread in the program tried to
  access descriptor zero.
- Convert to use kmem_alloc/kmem_free.
