okay, applied O10 on top of 2.6.0-test2. The same problem I wrote you
yesterday about O9, when starting OpenOffice and bzip2'ing in the
background OO becomes nearly unusable - I can type a sentence and watch
the characters appear. I don't know if this was always the case since I
haven't used OO before that much (need it for the university now)
