Code review comment for lp:~vlad-lesin/percona-server/5.6-sql_timeout_twitter

First option obviously wouldn't work because there are additional PFS-specific tokens which are generated automatically (in gen_pfs_lex_token.cc) with IDs starting from max last token seen.

Maybe it isn't that bad to update test cases with new digests. I just wondering why that method of digest calculation has been chosen. Probably nobody should refer to digests in their scripts/applications/etc, and they are needed only for internal purposes.
