Why are we using a range of 0 to 100 anyway?  100 seems like an arbitary 
value for kernel space - why not just keep it as a value in the range 
[0,2^32) ?   That eliminates the arbitary constant of 100, and in some cases 
could reduce the effects of rounding and allow finer control at no 
additional expense.
