Description:
The `buf_resize_thread` should be in the performance_schema.threads table.

How to repeat:
select thread_id,name,thread_os_id from performance_schema.threads;

Suggested fix:
A `pfs_register_thread()` call should be added in `fts_optimize_thread()`.

Here is the fix: https://github.com/mysql/mysql-server/pull/350

To clarify,

incomplete performance_schema instrumentation is considered a bug,
because it affects the quality of stats returned by the performance schema.
