Sorry I've been so long in responding.  I'm a tad swamped right now.  I
did look at your original code, and though there were a few things I
thought might be tweaked, nothing was glaringly wrong.  You may well have
found an error in the library, but I need a lot more time to evaluate
this.  The boost::condition is the most complex implementation on Win32 of
all of the Boost.Threads code.  It's a very tricky thing to emulate this
concept correctly, unfortunately.  I don't think I'd be too quick to blame
the problem on the OS, since the OS doesn't have conditions.  It's much
more likely that the problem is either in the test code, or in the
Boost.Threads library.  Give me a few days to evaluate this one
thoroughly.

Oh, and thanks for the other example as well.  I haven't looked at it yet,
but having two examples is likely to make it easier to track down the
issue.
