I'm actually agreeing with you! I just think that alot of people are used
to using pthread_t carelessly, which lets them use it just like a 32 (or 64)
bit integer, etc.

This is, of course, exactly the kind of place that Boost.Threads will make
concurrent programming less error-prone and more portable.
