Nothing, but I don't mess with things I don't understand :) Changing
randseed (and makes absolutely no change except if your random generator
might be bad ;)) during random number generation is really a bad idea:

c:\>test
Length(psData) = 200401
ByteValue: 187
Length(Source) = 200401
First Loop....
elapsed time: 6751

c:\>test
Length(psData) = 200401
ByteValue: 174
Length(Source) = 200401
First Loop....
elapsed time: 60
