+# Wrapper script to allocate a port and fork a broker to listen on it.
+#
+# Instead of this:
+#  qpidd --port 0 <qpidd-args...>
+# do this:
+#  qpidd-p0 <qpidd-args...>
+#
+# The port is bound by python code, and then handed over to the broker via the
+# --socket-fd option.  This avoids problems with the qpidd --port 0 option which
+# ocassional fails with an "address in use" error. It's not clear why --port 0
+# doesn't work, it may be to do with the way qpidd binds a port to multiple
+# addresses on a multi-homed host.
