It won't matter. 90% in EGTB accessing will be used for fread(). There is not
much potential (one could say practically no potential) for PGO for EGTB access.
At least not in positions I tried and rather carefully profiled (this included
positions, where over 90% of the ovarall time was used for TB probing). Perhaps
with really fast disks, the situation is slightly different, but still, the
potential for PGO will be very small here.
