Interactivity is still worse under ULE. It's quite noticeable and I
tested it on two SMP boxes by running two simple loops in kind of:
for ((;;)); do let $((4+4)); done # this is bash specific

The loops ran under nice +20. Typing in the xterm is jerky,
characters will not show up immediately, but in small "bursts". I
mean that about three characters typed in will show up immediately,
then small pause happens and a burst of characters (which queued up
in the pause) will show up. This is annoying. Starting up xterm
takes more time as well, but I can live with that.
