Example Profiling document for WT:

}
Notice that execStats.saveState and execStats.restoreState is 0. It is always 0 for all the documents. It seems to be related to yielding and since numYield was suppressed from WT (SERVER-16020), we should probably suppress execStats.saveState and execStats.restoreState .
