 - macOSX : we use an unused TLS slot from the OS allocated slots (MI_TLS_SLOT). On OSX, the
            loader itself calls `malloc` even before the modules are initialized.
 - OpenBSD: we use an unused slot from the pthread block (MI_TLS_PTHREAD_SLOT_OFS).
-- DragonFly: the uniqueid use is buggy but kept for reference.
