I restarted the make this morning but could no longer recreate the issue for 
Linux and Windows. There is another issue with Mac, but that is caused by an 
rsyn error.

I still have the output from yesterdays make:

I logged into it as you suggested and called halt. The ssh connection dropped, 
but the quemu process kept running:

user at host:~$ ssh -oNoHostAuthenticationForLocalhost=yes -i ~/make/gitian-
builder/var/id_dsa -p 2223 root at localhost

The system is going down for halt NOW!

My uname output is:
