This appears to have broken the dashboards - the graphs now
periodically flash up error messages. On the console this coincides
with:

2016-06-02 13:50:37,494: ERROR pgadmin: Exception on
/dashboard/tps_stats/1 [GET]

KeyError: 'template_path'

(or a similar error about another member in server_info).

I'm guessing this means that data is not being made available to each
thread? We need to fix this ASAP so we're ready to release tomorrow.
