Webscrape parallel requests problem

[gilesknap]

My PoE switch cannot cope with MAAS interacting with two machines simultaneously. We are interacting with a single instance of the switch's Web GUI so this is not a surprise.

Possible Fixes -

• use a critical section to only allow one interaction at a time
• launch an instance of the GUI for each device controlled.

in fact it can cope with parallel queries.

But I cannot believe that a parallel off or on would work
