Let's not try to imagine what happens when he would have had a
commercial program.

Note that i used about 184mb RAM in 3 different caches with EGTB
information stored.
  - 150mb transpositionhashtable ==> i store EGTB there too in a special way
  - 2x2mb egtb cache
  - 2x15 mb wasted for just the egtb indices as i'm dual processor.

Note i probe also in the qsearch which most people don't do. I initially
didn't do it either but then started drawing some games on the internet
because i didn't do it.

But for sure i don't want to waste another 16mb RAM from the expensive
RAM i have now for another EGTB cache.

Instead more likely is that i convert the EGTB to my own format after
which users who usually don't have an additional 15mb for egtb indices
to let them do without.
