Swap space requirements on 10g installs - must it really equal RA M?

Hello, When installing 10G on dev and QA I had gotten the error that we should configure swap space to equal RAM. Since I figured out 4G of swap space was more than enough (why would we need 16G of swap space?) I ignored it, installed the software, created the database, and had no problems. But one of the other DBAs was doing the production install and when he saw the message he balked and opened a TAR with Oracle. The Oracle support tech said that you *should* have swap set = to RAM. To be precise they said: "...the database should not be installed on a machine having less than a 1:1 ratio of RAM to swap. I would not advise skipping this message." Speaking with one of the SAs he said the system won't even recognize more than 4G of swap. Does anyone know of any reason why we would need more than 4G of RAM or (preferably :) why this isn't really important. Documentation for the latter would also be nice as I would now have to convince my management that this isn't necessary even though Oracle said it was.
