This patch affects only code used by :sigio and :fd-handler
communication styles, not code used in the :spawn style.  If you'd like
to try the patch, please pass `:style :fd-handler' to create-server,
which is the default on SBCL when threads are not available, or set
*communication-style* to :fd-handler before creating a server.

I am not experienced with SBCL, but the :spawn-style-related code seems
to close the connections correctly.  I am not sure how the
"auto-flush-thread" is operating, but would be slow to blame it before
something in the :spawn code.
