+Subject: [PATCH hurd] trans: improve demuxers
+
+Handle multiple request types as recommended by the Mach Server
+Writer's Guide section 4, subsection "Handling Multiple Request
+Types".  This avoids initializing the reply message in every X_server
+function.
+
+* trans/proxy-defpager.c (proxy_defpager_demuxer): Improve the demuxer
+function.
+* trans/streamio.c (demuxer): Likewise.
