Bug#110015: FS server crashs a subhurd

[Roland McGrath]

Hmm.  So what is PID 2 in your sub-hurd, if it's not the kernel?  It's true
that a sub-hurd should probably not diddle the kernel task as the boot hurd
does--but I don't know a reason it shouldn't work.  I am still confused as
to how this crash happened.

Just use ps options to ignore unregistered tasks when you are looking.

At some point we might want to make `boot' give a fake host-priv port and
then do things like report a subset of tasks to the sub-hurd.
