	* src/client.c (do_exit_status): Don't call channel_eof. This way,

	(init_channel): Set CHANNEL_CLOSE_AT_EOF by default.
	(channel_read_close_callback): Improved comment.

	* src/channel.h (CHANNEL_NO_WAIT_FOR_EOF): New flag.

	* src/server_session.c (spawn_process): Clear

	* src/io.h (SHUTDOWN_UNIX): Moved shutdown workaround from io.c,

	for AF_UNIX sockets only. 

	* src/scm/gaba.scm (string-upcase): Moved definition to
	guile-compat.scm. scsh already provides string-upcase, and the
	definition here trigs a bug in string->list in scsh-0.5.2.
