This somewhat reminds of the following software optimization procedure: - Let's thread this thing. - OMG things are working N times faster (where N=cpus) - 1 year later, shit... In 0.1% of the cases there is race condition and we can't figure it out, random garbage to our data... - 1 week later rolled back to single thread and now everyone is complaing why things are slow... - This actually happened... (just not the same time frames)
