If you are running a relatively recent version of IDL, I really don't
think you have to worry about this. They recently overhauled the way
they generate the initial seed to make it more robust. You would have to
ask the folks at ExelisVis, but if it were me, I could find a couple of
hundred things more compelling to worry about, starting with high
avalanche danger on my favorite skiing trails after a weekend of big
snows.

Cheers,

David
