Note that in case problems persist, a testcase is *required* for anything
concrete to happen. It's impossible to diagnose in any serious detail
thread-safety issues without knowing the code, trying it's just a huge waste of
time, we know that. Also note, just in case isn't already obvious, that C++98
doesn't talk about threads *at all*, thus very little is guaranteed in a
non-implementation defined way.
