tools: Rate limit operation and fix strange buffer issues
Slightly relaxes the necessary amount of memory, as we are no longer loading everything all at once. Also for unknown reasons git interferes with other git processes running in the same repository only on Linux. This causes Linux runs of this tool to have strange issues detecting the authors, as git just quits with a success error code. Fun.
