It isn't just cygwin, it also happens with Mac OSX. What happens is that
you are getting the EAGAIN flag from the operating system, which is not
handled by the SimpleHTTPRequestHandler.
In my split-storage-2 branch, I rewrote the handler slightly so that it
will retry EAGAIN failures.

I also decreased the socket timeout value, because in my split-storage
branch, I have enough tests that I spawn about 30+ web servers, and
waiting 30sec for timeouts is longer than the rest of the tests take.
