Using Multiple Worker Processes (Web Garden) within one Application Pool

I've read all over the internet NOT to use multiple worker processes within one application pool.  That it's only used under very special circumstances.  I just can't locate the "hard resources" that outline the reasons why not to do it.  I need verifiable resources I can send out links to because unfortunately I have colleagues at work forcing my hand.  They don't want to just take my word that sessions can get mixed between the workers causing tons of issues.

anyone got links to verifiable resources that explain the ins and outs and the CONS of not using a web garden within one application pool?
