[Rev 02] RFR: 6643: Make VM Operations rule consider close consecutive events in score

[Jessye Coleman-Shapiro]

> This patch modifies the VM Operations rule's score calculation so that is considers blocking that could result from the combination of multiple close consecutive operations.  Right now an application's score only takes into account the longest event in its calculation. 
> 
> At the moment I have determined two events to be "close" if they occur within 0.01 s of one another.
