  Modified files:
    sys/kern             sys_pipe.c 
  Log:
  Fix some lock ordering issues in the pipe code.
  
  In particular fix a bug in the pipe_write() code when multiple writers
  are present that could cause garbage to be injected into the pipe due
  to a resize possibly occuring while wpipe->pipe_buffer.cnt is non-zero.
