Subject: [PATCH] tools: replay next2c's sporadic frames with coherent
 maintenance

The quiet desktop's sporadic heavy frames (next2c: 3 IBs a second,
57.9 copies/s) with b12v23's coherent maintenance: the kext time per
IB falls from 13 ms to 6.5-8.5 ms (the preparation stays), and the
model then delivers every refresh (59.5 copies/s) in every mode, so
the adaptive mode never engages there.
