Key pool

New public and private keys are pre-generated and stored in a queue before use.

This pooling feature was added so backups of the wallet would have a certain number of keys that would be used in the future. By default, the number of entries in the queue is 100[1].

A command line option allows a greater or lesser number of keys to be maintained in the keypool[2].
