Comment (by teor):

 We should disable this new feature on small networks.

 (For example, if the limit is 5%, but the number of relays is less than
 20, it is mathematically impossible to achieve the limit. And if the
 number is slightly more than 20, the weights are going to be very skewed.)

 We should also think about whether we want a hard-coded limit, or we want
 the limit to be a consensus parameter. It would be annoying to have to add
 a consensus method every time we decide to change the limit.
