I had basically concluded the most we might do is just warn on smaller heaps at startup, but I also realize that isn't going to really matter much either. I just thought it would be a way of shutting down complaints that we changed the guidance on this without warning.

I agree that changing Out of Memory to "increase your heap size" is kind of silly. As long as we're suitably loud about what the failure was (failure to reload the metadata).

I wish there was a CRIT category like the SP has.
