Bug#770135: Bug also present in systemd 215-17+deb8u2

[Alistair Turnbull]

I too am seeing 25 second delays when I log in by ssh. I can turn 
the problem on and off exactly as described in #86:

 	https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770135#86

When the problem is "on", many things are broken in addition to slow ssh 
login. The "shutdown" and "reboot" commands do nothing. Starting and 
stopping services fails with a timeout. The latter in turn often breaks 
"apt-get upgrade".

Sometimes the problem turns "on" when the server has been up for a long 
time. I don't know what event triggers it.
