jabber.sl.o is XS 0.5.2 stock install. It has 2GB of ram. Both xsdev and
jabber.sl.o are virtual machines on the same network in the same rack.

connected-users reported the correct number, so when they were disconnecting

We were using the Analyze activity to compare. On the 0.6 server it matched.
I was watching the server and Analyze at te same time.

olpc-xos command is not installed on SoaS. Maybe we can add that. Using
analyze we can see the real-time connection but I don't see any way to
capture the data historically.
