First git branch

I just created my first git branch of libxr with the command line:
# git checkout -b non-blocking
# git commit -a

Of course, the first commit is a patch which turns libxr back to non-blocking I/O. The next step is to setup the time out value of waiting incoming HTTP header.

BTW, I am also planning to spare sometime writing a document about libxr, with XeTeX.
