Looks like only me in there.  Unless another user did something and then 
exited.  Is that possible?

The plot thickens.  PA *was* started today and it has since crashed.  I 
didn't notice that it had crashed until Pidgin croaked.  One possibility 
is that I have started up a KVM instance since this morning.  Any link 
there, possibly?
