Since it's an information leak, this is not something we want to expose as an
interface. It's also a very ugly interface: why not just *clear* the sample,
instead of dropping it?
The hardware messed up and gave us something we specifically did not permit
user-space to collect. We have to fix the bad effects to the best extent we
can,
and not based on some knob.
