I've implemented boost.fiber on top of boost.context - it aims to be a
light-weight-process (with scheduling etc.). boost.fiber provides some
channels too which can be used to exchange data between fibers even if
they are running in different threads (fiber blocks/yields if it is
waiting on a channel and gets resumed -> special mutex and condition
I don't know if the channels of boost.fiber conform to CSP.

I try to provide similiar functionality to C++.

I didn't knew libtask - seams similiar implementation is C (despite the
fact of differences in assembler).

Unfortunately XP is still my developing platform (have no access to
Windows7 etc.). Maybe it could be a fallback.
