Nice level versus posix static priority level debate aside, this
is the exact behaviour which the compat mode does now basically,
when you have all tasks running at nice 0 (which I assume is the
essentially the case in both the jvm and firefox tests) (some
things, eg. kernel threads or X server could run at a higher prio,
but these are not the ones calling yield anyway...)

I don't think it is a question of POSIX being a bit fuzzy, or some
problem we have implementing it. It is explicitly specified to
allow any behaviour.
So the current default is not wrong, any more than the compat mode
is right.
