Is there an actual proof anywhere? Yes, but I'm not sure where it was proven; try these references: T.J.Chaney, A Comprehensize Bibliography on Synchronizers and Arbiters Technical Memorandum # 306C, Institute for Biomedical Computing, Washington University, St.Louis T.J.Chaney, C.E.Molnar, Anomalous Behaviour of Synchronizer and Arbiter Circuits IEEE Transactions on Computers, Vol. C-22 (1973), pp. 421-422 L.R.Morino, General Theory of Metastable Operation IEE Transactions on Computers, Vol. C-30, 2 (1981), pp. 107-115 Most of the work is being done at Washington University, you should contact either Chaney or Molnar for further information.
