  Modified files:
    sys/kern             kern_sig.c 
  Log:
  - Change CURSIG() and postsig() to require that the proc lock is held
    rather than grabbing it and releasing it themselves.  This allows callers
    of these functions to get the lock to close race conditions.
  - Grab Giant around ktrace in postsig.
  - Count the switches performed on SIGSTOP's as involuntary context switches
    in the resource usage stats.
  
  Reported by:	tegge (signal race), bde (missing csw stats)
