  Log:
  MFC: Close some races between procfs/ptrace and exit1() by changing
  exit1() to block until any current PHOLD's are released.  This includes
  Simplifying the cleanup code in kern_ptrace() and removing the now
  unnecessary vmspace ref counting magic from proc_rwmem().  Also, the
  locking for ptrace_single_step(), ptrace_set_pc(), and
  ptrace_clear_single_step() have been fixed to be consistent across the
  tree.
