"Over 67 percent ... lock heaps" does not restore original monitor status when resolved ...

When InnoDB monitor output to the error log is enabled due to long semaphore waits, the original innodb_status_output setting is preserved, and restored when the auto-monitoring phase ends.

With "67% lock heaps" on the other hand, innodb_status_output is just set to false, regardless of the original setting.

So in the later case, if a user had explicitly enabled innodb_status_output on the SQL variable level, such setting would honored in the long semaphore wait case, but not the 67% lock heaps case.
