"Socket wrapper for Windows, which does not support dup()."

# (And hence, fromfd() and makefile() are unimplemented in C....)

# XXX Living dangerously here -- close() is implemented by deleting a
# reference.  Thus we rely on the real _socket module to close on
# deallocation, and also hope that nobody keeps a reference to our _sock
# member.
