Hi Andy,

It seems from looking at the code that create_v4 will create
identically the same guid if two computers (or nodes in a parallel
computer) create a guid during the same second? This would be very
common in any parallel program. This is why the paper you cite
suggests using the MAC address of the computer for the lowest 6 octets.
