per_socket_clients usage

[John Center]

Hi,

I'm in the process of upgrading from v1.1.6 to v2.1.3, & I've been 
reviewing the 2.1.3 config files.  I don't understand the purpose of the 
per_socket_clients config item in radiusd.conf.  I think I understand 
how this is configured, but what is this used for?  What benefits does 
this provide?  Is it for security, server resources, etc?

Thanks.

	-John
