  This should not be happenning with the ranking room Pachi instances
since they use dynamic komi.

  PachIW (which BTW seems to be seriously aspiring to 2d rank thanks to
the new pattern code and other new heuristics!) is not using the dynamic
komi code due to some problems with recent modifications of the code.
Because of that, it may resign H9 games because the initial winrate is
too low.

  Patches for this are welcome, but I'm unlikely to look into this
myself, especially since this should not be an issue with dynamic komi.
At least I hope so!

  It should not affect rating since at most H6 games are ranked on KGS.
