 Description   

This documentation isn't clear on how many connections a 'mongos' makes.

The correct number is:

 #incoming_connections + ( #incoming * #shards) 

OR

 #incoming_connections + ( #incoming * (#shards * #nodes_per_shard) ) 

if slaveOK/Secondary reads are allowed

The current doc could be read as saying the number is

 #incoming_connections + #shards

which is incorrect
