if kvm_nlist() fails, nlisterr() would be called before the screen 

curses context would be initialized; just use errx() instead in this case
this fixes coredump for cases like 'systat -N /netbsd.gz', reported by Walt
on port-i386

in nlisterr(), wait a while (5 seconds currently) before exiting, so that
it would be actually possible to actually see the error
