You've almost got it there.  The only problem is you're trying to disable
something that isn't already enabled.  What you need to do is have something
like:
		if ((status = smg$enable_unsolicited_input(&new_pid, kbdattn,
		     	new_pid)) != SS$_NORMAL) exit(status);
between the creation of the pasteboard and the call to
smg$disable_unsolicited_input, with kbdattn the address of a routine to
service the ast's.
