This is the _key_ point of condvar mutex use. Because it is guaranteed 
noone else can go in between
it is by no means easy to implement it e.g. on the windows platform. 
Luckily however some clever
guys have solved this problem. :-)

Again, I highly recommend to get a book on pthreads. You will find a lot 
of useful information which
also applies to boost threads.
