Um, this bit is *not* right:

+           ((unsigned int) MyStartTimestamp >> 20));

You're cutting it down to 32 bits and then right shifting, which
means you are shifting in a lot of zeroes when you could be shifting
in something that's not quite as predetermined.  I had in mind to do
the shifts in uint64 arithmetic and then narrow the final XOR result
to int (maybe let the compiler do that implicitly).
