I read MSDN and wasn't sure exactly what 'a handle to the file used to 
create the calling process' meant.  I guess I guessed wrong.

Maybe not much, since feeding it 0x1000000 (which is the address where 
CoreAVC is loaded) works. Perhaps I could create a dummy stub to return 
in this case.  I don't know what is supposed to be in memory at the 
beginning of the file handle though.  Do you know if this is supposed to 
be mapped to a structure?
