"As of MySQL 5.7.6 (...)
May allocate additional memory during server operation"

But http://dev.mysql.com/doc/refman/5.7/en/performance-schema.html still claims

"No memory allocation is done beyond that which occurs during server startup. By using early allocation of structures with a fixed size, it is never necessary to resize or reallocate them, which is critical for achieving good runtime performance."

which is incorrect since 5.7.6.

How to repeat:

Suggested fix:
Remove the contradicting statement from http://dev.mysql.com/doc/refman/5.7/en/performance-schema.html
