That's funny because...

... this should have the same effect as MALLOC_CHECK_, i.e. it should
enable the extra checking and slow things down in the same manner as
MALLOC_CHECK_. However, it looks like we don't do __malloc_check_init
for M_CHECK_ACTION, which is what initializes the additional checks.
Does anyone know if it is intentional? It looks like a bug to me.
