From tracing there a timer wakeup each second but before we had a wakeup
each jiffy because we could not lookup the next timer without taking the
base lock which we can do now.
However if there is room for improvement to have a wakeup every two or
five seconds I am all for it because from RT point of view we should be
able to do the same things as the non-RT version.
