// Since automation setup isn't synchronous, we can be tearing down while
// being only partially set-up, causing even synchronous IPCs to be dropped.
// Since the *Chrome* startup/tear-down occurs synchronously from the
// perspective of automation, we can add a flag to the chrome.exe invocation
// in lieu of sending an IPC when it seems appropriate. Since we assume this
// happens in one-off fashion, don't attempt to pack REMOVE_* arguments.
// Instead, have the browser process clobber all history.
//
// IE8 on Vista launches us twice when the user asks to delete browsing data -
// once in low integrity and once in medium integrity. The low integrity
// instance will fail to connect to the automation server and restart it in an
// effort to connect. Thus, we detect if we are in that circumstance and exit
