    sys/kern             sys_pipe.c 
  Log:
  fix a problem referencing free'd memory.  This is only a problem for
  kqueue write events on a socket and you regularly create tons of pipes
  which overwrites the structure causing a panic when removing the knote
  from the list.  If the peer has gone away (and it's a write knote), then
  don't bother trying to remove the knote from the list.
