	* ext/socket/init.c (wait_connectable): break if the socket is
	  writable to avoid infinite loops on FreeBSD and other platforms
	  which conforms to SUSv3.  This problem cannot be reproduced with
	  loopback interfaces, so it's hard to write test code.
	  rsock_connect() and wait_connectable() are overly complicated, so
	  they should be refactored, but I commit this fix as a workaround
	  for the release of Ruby 1.9.3 scheduled on Feb 24.
