It's only an issue within the same pool - so having 'allow' in one 
pool and 'deny' in another pool is no problem.

The problem isn't that the server doesn't handle it, it's that the 
way a mix of allow and deny in the same pool interact - it is defined 
but non-obvious (and I can't recall how it works anyway !).
