Come on, you can test a lot more than that. Even if you only test
create and open functions, if you test the various case combinations,
with or without the CASE_INSENSITIVE flag, for mutexes, events,
semaphores, pipes, mappings, files, etc. you should be able to easily
come up with a few hundred tests.
