This can be a server issue or an InnoDB issue.

Posted by developer: In the work to move system tables from MyISAM to InnoDB, information about plugins now have to be looked up in an InnoDB table. The way --help --verbose is implemented, is not optimal wrt to performance, but will require quite a major effort to improve. Short term, at least, we do not plan to fix this.

Noted in 5.7.8, 5.8.0 changelogs. mysqld --help --verbose tried to perform actions that have nothing to do with displaying a help message: Locking files, initializing system files, and checking for a plugin table.
