instantupdate needs refactoring to cope with socket server outage

[kaihendry]

During some critical maintainance https://twitter.com/webconverger/status/656963368247427072 a customer complains:

They kept opening up new tabs over and over until there was a kernel panic error. 

Yeah I rebooted them and they would just open new tabs over and over
until they gave the error on a black screen. 
Had 5 stations all do the same thing. I had to revert back to our
previous software for the night. I will check them in the morning to see
if they are working.
