- wxSocket no loner automatically Closes() the socket when it receives a

LOST event.

- Elusive bug found and fixed when:
a) there was still data to be read in the input buffer, but
b) the socket had already been closed by the peer, so
c) there was a LOST event before the next INPUT event was generated.
