+ This parameter is read when a seed function is called,
+ and then kept in generators state object. It has a rather
+ small default value that causes reads of strong random bytes
+ about once per hundred calls for a random value.
+ The set value is rounded up to an integral number of words
+ of the size these seed functions use.
