    sys/vm               vm_map.c vm_map.h 
  Log:
  MFC: part of vm_map.h rev 1.68 and vm_map.c 1.212.  This is actually
  a prequisite of the vm_map.c rev 1.280 that dillon prematurely MFC'ed
  on Jan 13th, 2003.  Without this change, the kernel leaks vmspaces
  to varying degrees depending on the circumstances.  Specifically,
  vm_exitingcnt was being copied from the parent to the child when it
  might have been non-zero.  This caused the child's vm_exitingcnt to
  never hit zero.  This was blowing up machines at work.
