	* api.1/lock.exp: Work around a race condition in the Solaris 9
	pty implementation: output sent to a pty slave immediately before
	last close/exit can get lost on the way to the master.  This is
	Sun bug #4927647.  The workaround consists of changing the tests
	to always make lock-test wait to read a character prior to
	exiting, so any output prior to the "wait" directive will not get
	lost.
