Subject:		[BUG][FIX] in platform specific code (unix/osx) for
socketValid, causes core dump

Comments:	This change prevents the following failure case where you can
create a  
socket before initializing the network which
then causes the VM to core dump after a save/restart when it attempts  
to destroy the socket say as a result of weak reference cleanup.
