FastSortedSet dupes? #45
Description
it is a possibility that FastSortedSet is tricked by kotlin coroutines into letting dupes slip by, particularly using kotlin comparators.
i this commit, the XOR class in tests is a sample where this would be studyable

a concurrentskiplistset and some minor adjustments does seem to rememdy the same code in the same concurrent situation, which will be present in later commits.
cheers.
