concurrentKanren: miniKanren for parallel execution

slides:none on file

concurrentKanren implements miniKanren in Golang and runs the search tree as actors, with a naive goroutine-per-node messagebased model that collapses under overhead and a bounded worker pool that uses task queues and matches the performance of faster-miniKanren on the tested queries. It preserves logical result order, implements immutable AVL trees with structure sharing for cheap thread-safe substitutions, adds generalized concurrent disjunction and conjunction shortcircuiting, and shows promising but workload-dependent speedups.
