So to clarify you want the procedure to either:
1. Close the socket normally
2. Fail to close the socket yet lose the file handle so the programmer can
do nothing useful with the socket when he/she handles the exception.

The second path seems like it would not be useful and it would be annoying
since it introduces an unusable exception to handle.  I conclude that you
want to the invalidate the handle no matter what (since it is a result of
both paths) so why do you not just silently ignore any errors given by the
OS?
