Public bug reported:

I'm seeing the following while trying to read meta-data from SmartOS.

2018-01-31 21:36:03,554 - DataSourceSmartOS.py[DEBUG]: Writing "V2 29 459961e2 d133c055 GET c2RjOnJvdXRlcw==

This seems to cause DataSourceSmartOS to fail completely, then it goes
on to time out on EC2 and CloudStack.

This is using my own build with this changeset at HEAD.
