Re: [boost] [asio] asio formal review

The ACE framework ( http://www.cs.wustl.edu/~schmidt/ACE.html ) is a fairly
well regarded cross-platform communications framework.  It is probably best
known for identifying and formalizing many patterns in communications
application design.  Some of these, especially the "Proactor" are clearly
visible in the asio design.

Unfortunately, ACE's current implementation is aggresively cross platform
(moreso than boost!), with so many macros that its implementation is barely
recognizable as C++.  Also, ACE is still an all-or-nothing proposition, with
no factoring to allow people interested in sockets to skip the pipe
implementations, etc.

When I say "ACE without the cruft", I mean it as a double-edged compliment -
solid design coupled with a clean implementation.
