I saw some brief discussion about enabling it by default, and recommended
against it. It causes extreme system instability for me. For example, in X,
if I start doing something cpu/io-intensive (like build.sh build), it's not
uncommon for it to hang the system completely for periods of time between 30
seconds and 2 minutes. Without NEW_BUFQ_STRATEGY, the problem goes away and
performance is fine. I don't think the tradeoffs are worth making it the
default ;-)
