You're welcome. The release mechanism is ad hoc. You can use subversion directly if you want to put that under your control.
The setup includes everything you need to debug the source, but I would encourage you to do a svn checkout and regular updates if you can handle a little entropy.
BTW, I learned that I should not be using ExitThread in a C++ dll that links to the static CRT. Just return 0 and the C++ runtime will take care of things. I've updated async.cpp to do that.
