# This class implements a thread that handles the networking connection.
# It expects a copy of the board and an open socket to the remote host, which
# it will bind to a GTPSocket.
# This is the only thread that should be calling get(), but send() could be called
# twice, so we wrap it in a mutex.
# The board is also wrapped in a mutex, even though only this thread should modify it
# if it exists.
