pci arbiter being killed

[Joan Lledó]

Hi Hurd,

I've observed how my instance of the pci arbiter receives a SIGKILL 
about a minute after start, it could be my fault as I've being messing 
around with gnumach, libpciaccess and the arbiter itself, but just to 
confirm: is not there any process that kills the arbiter after a while 
of not being used? and how could I know who is sending the SIGKILL?
