Bring more overhead to kernel if we zero the bits considering the number of

Keeping the samples at least allows you to know how many samples
happened and such things.
And the skid information may be interesting (see example of hitting on
page_fault in previous mail). If we zero it, we will not know.
If you throw them out the window you also don't know, do you?
