Have you tested this?  I don't think it's quite right.  According to the
urlgrabber docs: "if it's an int, it's the bytes/second throttle limit.
If it's a float, it is first multiplied by bandwidth."

Also this would only set the initial throttle...if you want dynamic
throttling, you have to set it per-repo.  Patch coming soon.
