Yes, starting from 3.23.5.

The macro is the following 

#ifdef SAFE_STATISTICS
#define thread_safe_increment(V,L) \
	pthread_mutex_lock((L)); (V)++; pthread_mutex_unlock((L));
#else
#define thread_safe_increment(V,L) (V)++
#endif

It's used for all statistic (not REALLY important) increments in
sql/handler.cc

Not that 3.23.6 has some fatal bugs;  I will release 3.23.7 tomorrow,
which should fixes the known problems i 3.23.6.

As soon as 3.23.7 has been out a week (without problems reports), I
will release 3.22.28, which also has the above macro.
(I can't release 3.22.28 yet, as it shares some libraries with 3.23.7
and I want to have these libraries checked before doing a new release)

Regards,
Monty
