in bug 1114647 a lot of work was done to change the process names for the child process, but in the act of doing so it appears we have missing data:
https://treeherder.mozilla.org/perf.html#/alerts?id=708
ni myself to ensure that I follow up here- so far I have been putting print statements in cmanager_win32.py to determine what is getting registered, it appears that on the first counter that we register, we never complete the addition of it, somehow we are hanging in a loop and never registering other counters in the loop, nor finishing the registration which then causes us to never start collecting.

we were throwing an exception in code that effectively looks like:
expanededCounters = None
expandedCounters.append(...)


this is easy to solve and when we do we go back to our previous values.
