Browse Source 
Just initialize drive data.
	* mtinfo.h (MTINFO_MAGIC): Remove.
	(MTINFO_VERSION): Remove.
	(class mtinfo): Remove magic and version members.
	* shared.cc (shared_info::initialize): Move call to
	get_session_parent_dir so that the dir creation is only called once.
	Move call to mt.initialize so that it's called only by the first
	process creating the shared memory.

	(CURR_SHARED_MAGIC): Ditto.
