Hello,
	I have an element that needs to keep a track of an average packet delay
and I would like to keep it in the kernel due to speed reasons.
Obviously I cannot use floats (to use the usual running average
equation) and the numbers wrap around pretty fas, hence the standard
method of an accumulator does not work.  Does anybody know how to get
this issue solved?


Many Thanks,

Roman
