 // Wow_helper.exe is a simple Win32 64-bit executable designed to help to
 // sandbox a 32 bit application running on a 64 bit OS. The basic idea is to
 // perform a 64 bit interception of the target process and notify the 32-bit
 // broker process whenever a DLL is being loaded. This allows the broker to
 // setup the interceptions (32-bit) properly on the target.
