What do you think? Before we start changing all the callers or the defaults, it would be nice to know we don't have other options. The reason I'm begging for a repro is to understand what's going and make sure we can't fix it on the lower levels. If we want to switch everyone to use non-memory-mapped files by default, we better have a very good reason to do so and know about the trade-offs. My hope is that we can get rid of this flag some day rather than put it into more places or change a default to something that seems less efficient (I don't have data, so that's an uninformed opinion).
