  Log:
  Initialize the count of saved register windows to 0 in the pcb created
  for the new thread.  The rest of the fields in the pcb wind up being
  written to before they're read as a normal part of the pcb usage but
  this field may be read upon return to userland, having it be uninitialized
  garbage is bad.
