Perhaps they were refering to something like what is done in the /dev/random driver, where inputs are mixed in using a simple polynomial scheme whose exact details (or name) escapes me at the moment. This is basically because it's called during interupts, and you might not want to be calling out to something expensive like SHA-1 right then. Then when someone reads from the device the output is derived from the internal pool using SHA-1.
