Yes a well known problem now (see other threads about wine). Wine doing
something very cpu intensive exhibits this due to a combination of wine
breakage brought out by my scheduler tweaks causing priority inversion.

Actually I've profiled acroread and it seems to be more a memory issue than a
scheduler one per se. Something very inefficient about it's design and it
behaves much worse as a mozilla plugin than standalone. Give it lots of cpu
time and it just keeps doing more and more vm work.

This is because of wine, not the Konsole which behaves fine, but tips the
combination of wine and something else over the edge.

I'm working on it. Thanks very much for your report.
