Lol 15years ago I fixed the same problem in some long running memory hungry multithreaded c++ application in same way .. and i was wondering why such hack was necessary and not default.. i remember reading some guide in some Google blog which was already dated by then... 15 years and not yet fixed(defaulted) ?
