+From cc50ca70e3b438577c33a85147e2a68666deaad9 Mon Sep 17 00:00:00 2001

+Subject: Create mux socket for regress in temp directory
+
+In some setups, creating the socket under OBJ may result in a path that
+is too long for a Unix domain socket.  Add a helper to let us portably
+create a temporary directory instead.
