No. The first check comes early - it allows us to reject the client 
immediately if there's no chance of it being allowed in.

Then, in the second check, we've already found the source that this client is 
being connected to, and we check again - this time, if the check succeeds, 
the global client count is incremented.

The first check isn't required, but it does allow us to reduce the amount of 
work done in the common case.
