Thanks for your patch! I see two issues with this feature: 1. Before, the single (default 64 KiB) buffer was allocated at startup. Now you will allocate a buffer each time a new console is opened. Depending on memory fragmentation, this may fail. 2. People with RAM-constrained systems may not like this. Can it be a config option?
