These tests use NM threads but NT is not freed for MN thread, causing it
to be reported as memory leaks in LSAN. For example:
#1 0x62ee7bc67e99 in calloc1 gc/default/default.c:1495:12
#2 0x62ee7bc7ba00 in rb_gc_impl_calloc gc/default/default.c:8216:5

#4 0x62ee7bc5cdbc in ruby_xcalloc gc.c:5215:34
#5 0x62ee7bdea4c6 in native_thread_alloc thread_pthread.c:2187:35
