It was empirically found that timings of references to primary memory
are subject to irregular, apparently non-deterministic variations. The
subroutines in question instrument these references for purposes of
-gathering entropy for random number generator. In order to make it
+gathering randomness for random number generator. In order to make it
bus-bound a 'flush cache line' instruction is used between probes. In
addition probes are added to B<vector> elements in atomic or
interlocked manner, which should contribute additional noise on
performs at most B<max> probes in attempt to fill the B<vector[num]>,
with B<max> value of 0 meaning "as many as it takes."

Return value of 0 indicates that CPU is not capable of performing the
benchmark, either because oscillator counter or 'flush cache line' is
