Possible 'who' bug?

Possible bug with 'who', or kernel?

I have a couple of entries listed when I do a 'who' that I can't seem to get 
rid of (other than rebooting).  I've even gone so far as to take my system 
down to INIT runlevel 1 (single-user mode) and kill all extraneous processes 
(so that only the kernel threads and the single-user mode bash shell are 
running) and yet I still always see:

My computer is still in this 'state' so if there is anything you want me to 
look at (yo get you some more debug info) let me know.
