+This is indeed a difference in the way sockets work on Macos.  The
+problem stems from Gonzalo's change r42660 that intercepts async
+socket IO in the threadpool and hands off to a single worker thread. 
+It is giving a plain socket to poll() before connect has been called
+(because the BeginInvoke method hasn't been reached yet).  On Linux, a
+select()/poll() on this socket for writing will succeed and the
+BeginInvoke method will then be called.  On Macos, the poll() will
+block indefinitely and therefore the BeginInvoke method (which in this
+case calls connect() ) will never be called.
+
+Reassigning to Gonzalo, so he can rejig his logic in the threadpool
+socket code.
