         * IMPORTANT NOTE
         *
         * The NIST test vector set includes several calls to
         * HMAC_DRBG_Generate() that are expected to fail with a
         * status of "Reseed required".  The pattern seems to be that
         * when prediction resistance is requested, any call to
         * HMAC_DRBG_Generate() is at first expected to fail.  After
         * an explicit reseeding, the call to HMAC_DRBG_Generate() is
         * retried, and on this second time it is expected to succeed.
         *
         * This pattern does not match the specifications for
         * HMAC_DRBG_Generate(): neither HMAC_DRBG_Generate_algorithm
         * (defined in ANS X9.82 Part 3-2007 Section 10.2.2.2.5 (NIST
         * SP 800-90 Section 10.1.2.5)) nor the higher-level wrapper
         * Generate_function defined in ANS X9.82 Part 3-2007 Section
         * 9.4 (NIST SP 800-90 Section 9.3)) can possibly exhibit this
         * behaviour:
         *
         * a) HMAC_DRBG_Generate_algorithm can return a "reseed
         *    required" status only as a result of the test
         *
         *      "1. If reseed_counter > reseed_interval, then return
         *       an indication that a reseed is required."
         *
         *    Since the reseed interval is independent of any request
         *    for prediction resistance, and since the reseed interval
         *    is not specified as part of the NIST test vector set,
         *    then this cannot be the source of the "Reseed required"
         *    failure expected by the NIST test vector set.
         *
         * b) Generate_function cannot return a "reseed required"
         *    status under any circumstances.  If the underlying
         *    HMAC_DRBG_Generate_algorithm call returns "reseed
