On FreeBSD 10, Errno::ENOTCONN isn't raised, but Ruby goes in an infinite loop because getsockopt(2) in wait_connectable() sets sockerr to 0.

Does anybody know why the following code in ext/socket/init.c is necessary?

            if (sockerr == 0)
                continue;       /* workaround for winsock */

Bug #9356: TCPSocket.new does not seem to handle INTR
https://bugs.ruby-lang.org/issues/9356#change-45236

* Author: Charlie Somerville
* Status: Open
* Priority: Normal
* Assignee: 
* Category: 
* Target version: 
* ruby -v: ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
TCPSocket.new does not seem to handle EINTR properly.

In the attached test script, I try to open a TCP connection to my server and make an HTTP request while a background thread continually sends a signal to the process.

This causes the #write call to fail with:

x.rb:13:in `write': Socket is not connected (Errno::ENOTCONN)
	from x.rb:13:in `<main>'

This also appears to affect 2.0.0. 1.9.3 is unaffected.
