StackThreads is now v0.3

[Mikola Lysenko]

StackThreads' context switching is now thread safe!

Also, the thread local storage template I posted earlier has now been 
integrated into the stack threads distribution.  There have been several 
small bug fixes and documentation improvements as well.  You can get the 
release at the usual place:

Future releases will improve compatibility with GDC on Mac OSX and 
FreeBSD along with performance.
