>Description:
	In the man DDB(4)
	     trace[/u] [frame] [,count]
     Stack trace.  The u option traces user space; if omitted, trace only
     traces kernel space.  count is the number of frames to be traced.  If
     count is omitted, all frames are printed.

     Warning: User space stack trace is valid only if the machine dependent
     code supports it.

	Actually, the first parameter for trace is pid. When pid is givven, the stack for the process will be printed out.
