How Large can the [domain_realm] Section Be?

[Henry B. Hotz]

Let's suppose that there is an easy way to deploy updated krb5.conf  
files to all clients.  (True for OSX under OD, it appears.)  Let's  
suppose that I have only one DNS domain, but two Kerberos realms, and  
I know the complete list of machines that are in the non-default realm.

How large can that list be before I have "problems"?  10's?  100's?   
1000's?  10,000's?

We can assume reasonably modern machines, like a 2GHz core 2 Intel  
with 2GB memory if you want to be that precise.
