here we have a summary of why this discussion has been going on for so long.

your assertion that "threads are not....." is outside of my experience in 
multi-tasking.  COMPLETELY outside.
Now I admit, that my experience with "antagonist multi-tasking" (where the 
tasks compete for resources without any regard for others sharing the 
computer) is almost non-existent.  It is, unfortunately, what has 
apparently been studied in great detail at the universities, because their 
systems all face exactly that problem (everyone want's all of the resources 
now and hang the rest, MY job needs to get done).
There is another form for which we (at Computer Automation) coined the term 
"cooperative multi-tasking" which is that used in embedded system.  That 
is, ALL of the programmers are at least aware of what other things are 
likely to be running, and it is important to get THE job done, rather than 
MY portion.

I believe that boost:threads is more suited to the cooperative than the 
antagonistic multi-tasking model.
We're not trying to write a bullet-proof OS with boost:threads (I sure hope 
not... C++ doesn't have the requisite constructs to do that)
We're trying to build applications which can cohesively use multi-tasking 
concepts in order to handle a given task.

my apologies for not seeing this earlier.
