Wow, that SL page is old.  Three years old.  I need to update it and put 
caveat's on it.  The problem is that I can't put a link to RedHat's page 
even though that is where I get the information.

We use RedHat's kernel with no changes, compiling it to be compatible 
with their kernel.  So whatever RedHat has listed for limits is what we 
have for limits.
