Actually, I'm not sure that "Unable to complete system-info.log" is related to the task failure. I expect system-info.log generation to fail sometimes and generate that message, but I would not expect it to cause trouble.
Summary: Intermittent IOError: [Errno 109] The pipe has been ended after Unable to complete system-info.log: <type 'exceptions.WindowsError'> → Intermittent IOError: [Errno 109] The pipe has been ended
Whiteboard: [stockwell needswork]
I don't understand what's going wrong here. The IOError is coming from resourcemanager, which also uses psutil...maybe there is some funny interaction between the two callers of psutil??

I notice that this only happens on Windows and, from the system-info perspective, we fail when querying the list of users. So, as a speculative fix, let's not worry about getting the users on Windows. (I'm cleaning up a little too, so there are fewer nested exception handlers in use.)

this seems slightly better- we can assess where we are at after this is landed and we get more data.
