Stupid question, probably, but when running the non-pre-loaded version,
are you sure all the same modules are being loaded? I'm wondering if there's
some set of modules that, for some reason, isn't being loaded by the
sequence of requests you're firing against all of your httpds to
get the servers "warmed up" to represent real-life state.
