maas cli commands fail if run at the same time as 'maas logout' for any other profile.

The setup where this bug is frequently seen involves a host which interacts with 4 separate MAAS servers. The host is a test driver and uses the maas cli, when a test is being run, to collect information about the nodes that have been allocated:
    1. maas login maas_A http://10.0.40.100/MAAS/api/1.0/ <apikey>
    2. <maas cli commands to query nodes>
    3. maas logout maas_A

Tests are run in parallel against all 4 MAAS server (maas_A, maas_B, maas_C, maas_D).

When the timing lines up is a way that 'maas logout' is called, for example against maas_A, within close proximity to maas cli commands against maas_B, maas_C or maas_D, the following error is reported back to the shell running the latter.

jenkins@finfolk:~$ maas maas_B nodes list

This bug can easily be re-produced by opening two shells that are logged into two different MAAS servers. Log out of one server and then immediately attempt to run a maas cli command against the other. A re-try will generally work, so it seems there is a small window when this occurs but not so small that it's hard to reproduce.
