Nicholas and DesertNet were so eager to fix the bug that they gave me access to their 24-ways for several nights (and built a very nice debugging environment) as the bug was not really obvious. gianni@ spent some time writing down a prof-of-concept and testing several revisions of the patch (with several different compiling options). pho@ stress-tested several revisions of the patch finding not-really trivial bugs. I really want to acknowledge these guys for the 'underway' hard work they perform and really want to hope to see other people following the same footprints. Testing is often as important as developing patches. Attilio --=20 Peace can only be achieved by understanding - A. Einstein
