I don't want to sound ungrateful, but couldn't we have defined these in
terms of Usecs and translated?
I mean I sometimes compile hz to be 1000 for some reasons..
this means that I have to reset all these values in my rc scripts.
As an example the kern.quantum variable that will always be the same
despite a redefinition of Hz. It's stored internally in terms of Hz but
exported in uSecs.
