Adresses pr #165 and issue #164 by @colesbury:

Browse source 
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.
