If you want to join, you don't create a detached thread in the first
place, and you don't need to detach in the destructor because the join
does the cleanup. Note I'm using POSIX threads definitions here.

I have a bad feeling that a lot of time is being wasted because some
people are talking Win32 and some are talking POSIX. I'm currently
printing out the MSDN docs to figure out the relation between the Win32
defs and the POSIX defs.
