          Description

          The __wt_random code to handle an uninitialized random state is broken, if you don't initialize the random number state, you get 0 as your random number forever.

          I don't think this is a problem because the WiredTiger library always initializes its random number generation, I noticed because the mongodb-3.0 branch's test/format code doesn't initialize its random number generator.
