This patch build failed /bson/oid/init_with_threads with the log:

C:\data\mci\bb708ee5103729f8b30626f4e56ef44e\mongoc\src\libbson\tests\test-oid.c:71 oid_worker(): precondition failed: 0 < bson_oid_compare (&oid, &oid2)

Investigate if this is a transient system issue, a bug in how the test is creating/managing threads, or a possible bug in libbson.
