If subprocess.call will do then I can report the same results, a
64 bit process, using 32 bit CPython 2.5 to call it.
 
Also if the programme (C#) is built with the 3.5 framework I 
get the same results, however interestingly there is no 64 bit 
build for the 3.5 framework (or at least I was unable to find one).
