This object acts like a hash object, with the following differences:
- It keeps a count (the .length attribute) of the number of bytes that
have been added to the pool
- It supports a .reset() method for in-place reinitialization
- The method to add bytes to the pool is .append(), not .update().

According to _Practical Cryptography_, chapter 10.5.2 "Pools":
"Pool P_i is included if 2**i is a divisor of r. Thus P_0 is used
every reseed, P_1 every other reseed, P_2 every fourth reseed, etc."
