Tuna 0.4.1 released

[curt <curt@...>]

Re-mailing an announcement I unwittingly tacked onto an existing thread:

Tuna is a multi-threaded API that allows task-switching at the c/c++ 
level -- http://northarc.com/tuna

0.4.1 Now includes support for Win64 architecture (what a fun week it 
was learning x64 assembly, interesting stuff!) and has some performance 
tweaks for even faster stack swapping. Also added a few more examples 
and included VC2005 build support as well as the VC2010

Some API additions too, its all updated in the manual

As ever, all feedback is welcome, including any suggestions for 
performance comparisons.
