Don't forget that indeterminacy is also important for tournament play, this
has been discussed on this list a couple of times, I believe.

What might be interesting is a compile time tournament option that turns
off all asserts, tracing and sgf tracing. Would certainly give a measurable
speed up.

(This is all far less important for tournaments than a good level adjustment
scheme that would reliably allow GNU Go to almost fully use the allotted
time in tournament matches, however.)
