    Your arguments were along the line of:

    * It probably doesn't break anything (except we had somebody report
    that it breaks their app)

    * If it does break something then they must be doing something stupid
    (I refuted that because there are several legitimate ways to use rt
    scheduling that is broken by this)

    * We have many other APIs and tools that don't conform to posix (why
    is that a reason to break this one?)

    * We should break the API to cater for stupid users and distros who
    create local DoS and/or lock up their boxes (except this is trivial
    to solve by setting sysctls or having a watchdog or using sysrq)

    So did I miss some really good argument, or do you really think the
    above arguments are a good reason to break the API? If the latter,
    then we have to just agree to disagree and I'll ask Linus to arbitrate.
    OK?
