    Well I applied your patch without the ones from Thomas Schlichter. Was
    is intended like that or should it be on top of Thomas patches?

    I haven't tested thouroughly, but on the first impression your patch
    didn't make things really better, that's why I stoped testing. I just
    did following test:

    Running prime95 as task taking 100% CPU) and started up mozilla and
    mailer. This took nearly endlessly. Deaktivating ACPI timer and things
    are fast again, ie. starting mozilla is like no background task is
    runnig. I dunno if it is a not 100% working patch or if it is Nick's
    scheduler, which I am using.
