>Description:

	"systat -iostat" (numbers mode) will coredump inside the curses
	library if the number of lines of 'history' exceeds 7 lines when
	using a large screen/window size. In my particular case, 128x44,
	with a total of 7 devices being displayed. The traceback looks
	like this:

#0  0x20026551 in __set_subwin ()
#1  0x20025c1a in wrefresh ()
#2  0x20024bf4 in wrefresh ()
#3  0x37f6 in display (signo=14) at main.c:207
#4  <signal handler called>
#5  0x200afaea in read ()
#6  0x2009da4d in __srefill ()
#7  0x2009d90a in __srget ()
#8  0x2002302d in wgetch ()
#9  0x2fde in keyboard () at keyboard.c:56
#10 0x3590 in main (argc=2, argv=0xefbfda38) at main.c:158
