BlockBot Increases CPU usage by about 10x on Beta 4

[Southpaw1496]

Generally, with no-one online, my server idles at about 10% (out of 200%). However, as soon as I add BlockBot, even just by itself, CPU usage spikes to 110% and stays there, while without it starts at 200%, then drops to 110% while it finishes starting up, then drops to 10% and stays. I can't see anything in the logs that would indicate anything amiss.
