I just rebuilt my system to see if the problem had perhaps been 
solved, but it's still doing it.  It doesn't cause any problems (the 
process doesn't look like it's doing anything, just not going away) so 
I am gonna just let the processes sit there.

(no response on this tty, so I close it).

On another tty I get this:

I don't have DDB in this kernel at the moment (it's remote and I
prefer the crash dumps) but I can put it in and try again if there's 
something you can use from it.
