So I finally got my hands on the DDJ issue in question.  The article on 
multiplexing does give me some ideas on how to revise my own IOCP 
library, which is something I had been putting it off until I found time 
to learn how /dev/poll worked.  I've got a lot going on so it may be a 
few weeks but I'll post something here when I've got it finished.

I'm not sure that much if anything would need to be done to provide 
support for IO multiplexing in Boost.  Both methods rely on the 
existence of a thread pool.  Each thread waits on a blocking call and 
then operates on the data returned.  This can all be done right now 
without any modifications to the Boost code.  I guess the question 
becomes, is there a need for such an IO library in Boost?  The nature of 
the project would demand a good bit of custom code for each platform, 
which isn't typical of Boost components.
