           Summary: Socket ConnectAsync, ReceiveAsync, SendAsync methods
                    and non-blocking sockets.

The implementation of the new socket async API doesn't seem to work very well
with non-blocking sockets.

ReadAsync fails with a WouldBlock error, ConnectAsync reports success even
though the connection is refused (on Linux at least, on OS X, it hangs
indefinitely). I didn't check SendAsync but I suspect it would also report
WouldBlock if the send can't complete immediately.

Here's a test case for ConnectAsync, let me know if you need a test case for
ReceiveAsync/SendAsync too.

Reproducible: Always

Steps to Reproduce:
1. compile test.cs
2. run test.exe
Actual Results:  
On OS X, it hangs.
On Linux, it reports "connect succeeded"

Expected Results:  
It should report "ConnectionRefused" (which it does with a blocking socket).
