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. > 3. -- It seems I can trigger the same kind of starvation by simply doing > large selects in a Konsole window.

Once it happens it's very hard to recover, 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.
