@def WAIT_STACK_LOGICAL_SIZE
Maximum number of nested waits.
Some waits, such as:
- "wait/io/table/sql/handler"
- "wait/lock/table/sql/handler"
are implemented by calling code in a storage engine,
that can cause nested waits (file io, mutex, ...)
Because of partitioned tables, a table io event (on the whole table)
can contain a nested table io event (on a partition).
Because of additional debug instrumentation,
waiting on what looks like a "mutex" (safe_mutex, innodb sync0sync, ...)
can cause nested waits to be recorded.
For example, a wait on innodb mutexes can lead to:
- wait/sync/mutex/innobase/some_mutex
- wait/sync/mutex/innobase/sync0sync
- wait/sync/mutex/innobase/os0sync
The max depth of the event stack must be sufficient
for these low level details to be visible.

Stack of events waits.
This member holds the data for the table PERFORMANCE_SCHEMA.EVENTS_WAITS_CURRENT.
Note that stack[0] is a dummy record that represents the parent stage/statement/transaction.
For example, assuming the following tree:
- STAGE ID 100
- WAIT ID 101, parent STAGE 100
- WAIT ID 102, parent wait 101
the data in the stack will be:
stack[0].m_event_id= 100, set by the stage instrumentation
stack[0].m_event_type= STAGE, set by the stage instrumentation
stack[0].m_nesting_event_id= unused
stack[0].m_nesting_event_type= unused
stack[1].m_event_id= 101
stack[1].m_event_type= WAIT
stack[1].m_nesting_event_id= stack[0].m_event_id= 100
stack[1].m_nesting_event_type= stack[0].m_event_type= STAGE
stack[2].m_event_id= 102

stack[2].m_nesting_event_id= stack[1].m_event_id= 101
stack[2].m_nesting_event_type= stack[1].m_event_type= WAIT
The whole point of the stack[0] record is to allow this optimization
in the code, in the instrumentation for wait events:
wait->m_nesting_event_id= (wait-1)->m_event_id;
wait->m_nesting_event_type= (wait-1)->m_event_type;
This code works for both the top level wait, and nested waits,
and works without if conditions, which helps performances.
