 // The basic idea is to allocate one page of memory on the child, and initialize
 // the first part of it with our version of PatchInfo32. Then launch the helper
 // process passing it that address on the child. The helper process will patch
 // the 64 bit version of NtMapViewOfFile, and the interception will signal the
 // first event on the buffer. We'll be waiting on that event and after the 32
 // bit version of ntdll is loaded, we'll remove the interception and return to
 // our caller.
