daan	a4ed63d127	Adresses pr #165 and issue #164 by @colesbury: ... On Mac OS, the thread-local _mi_default_heap may get reset before _mi_thread_done is called, leaking the default heap on non-main threads. Now the current default heap is also stored in mi_pthread_key (or mi_fls_key on Windows). The _mi_thread_done function is called with this value.	2019-11-13 17:22:03 -08:00
