In past, OOM bug report havn't beed stopped. Why can I believe any miracle 
occur?

The fact is, any heuristic change have a risk. because we can't know
all of the world use case. then, I don't think we must not change anything
nor we must not makes any mistake. I only want to surely care to keep
trackability.

OK. I also aim to provide good and productive information. But I also 
have requests.
Recently mainly Oleg pointed some race and heuristic failure. I don't
want your engineer ignore such bug report. please help bugfix too, please.
otherwise, I'll upset again.
