Detailed Description

Note:

Use SG_ASSERT so that the assertion handler is used to dump the state of each thread when an assertion fails.

Bug:

Running with assertions and a non-zero knowledge threshold in lock-free mode will cause some assertions to fail. In particular, the way we handle terminal states (by deleting all children) can cause SgUctChildIterator to discover it has no children (in SgUctSearch::UpdateRaveValues and SgUctSearch::SelectChild) which it asserts is not true. It is also possible for threads to play into filled-in cells during the in-tree phase.
