Unfortunately I've no access to Mac OS -s o it wouldn't currently 
compile on Mac OS. I didn't test the preformance because I replace the 
current implementation of context switch (ucontext_t on UNIX and WIN 32 
Fiber API) with assembler. If this is finished it should work much 
faster because it preserves only the required registers and does not 
save the signal mask (which involves an system call). By this way I can 
provide an implementatio nfor Mac OS too.
I've an git repo which contains the boost-1.42 with additional libs - 
boost.atomic, boost.move, boost.fiber and boost.task. It is available 
from http://gitorious.org/boost-dev/boost-sandbox.
