netbase does not configure and many packages depend on this.
ifupdown (unreleased) is configured and replaces netbase.

Seems to be locked somehwere in thread_block in

if (notify)
   hyp_event_channel_send(nd->evt);
simple_unlock(&nd->pushlock);
thread_block(NULL);
hyp_grant_takeback(gref);

i.e. dom0 doesn't release the grant ref. Sending trafic on the same
bridge makes it progress a bit.

Looks like ethernet_xmit() is actually hanging, thus keeping the mutex
locked.

awoodland: hmm I seem to be able to repeatably cause /hurd/pfinet to hang by running 'apt-get source icedove' in an NFS directory
awoodland: at least I think it's pfinet that's hanging because I can't ping the box any more
awoodland: and no applications that send/receive over the network work on the hurd box either
awoodland: console applications continue to work
